To reproduce it, you could just set a very large ilimt/blimit for some user, for instace:</p> <p>lfs setquota -u user_foo -b 0 -B 0 -i 0 -I 17293822569102704639 /mnt/lustre</p> <p>patch for master: <a href="http://review.whamcloud.com/1890" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/1890</a></p> <p>Niu</p> <p>Does that mean that it should be possible for the customer to workaround this issue by identifying which jobs use a "too high" limit and correcting it to something within an acceptable range and thus remove the need to apply a patch? If so, at what threshold does the value become problematic?</p> <p>Thanks</p> <p>Peter</p> <blockquote> <p>Does that mean that it should be possible for the customer to workaround this issue by identifying which jobs use a "too high" limit and correcting it to something within an acceptable range and thus remove the need to apply a patch? If so, at what threshold does the value become problematic?</p></blockquote> <p>This patch is necessary, we shouldn't restrict user to set high limit, and the threshold limit which can trigger the overflow depends on many factors: ost count, quota_qs_factor (default is 2), quota_boundary_factor (default is 4), so there isn't a static threshold.</p> <p>Assuming there are 100 osts, the blimit less than 100P bytes should probably be safe, and the ilimit could be larger (since there is only one mds), say less than 1000P inodes or so.</p> <p>Niu</p> <p>I understand that we want to fix this issue for a future release, but I just mean that the customer may prefer to workaround the issue rather than to apply a patch as a more immediate way to avoid the issue. If the customer were to provide the three values you mention ( ost count, quota_qs_factor, and quota_boundary_factor) would you be able to calculate the threshold more precisely?</p> <p>Thanks</p> <p>Peter</p> <p>Could we ask to the customer what is the highest quota limit set for users/groups?<br/> As Niu stated, this patch only makes sense for very large quota limits.</p> <p>A workaround could be to just disable the dynamic qunit size feature by running the following command on the MDS before re-enabling quotas:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre># lctl set_param lquota.*.quota_switch_qs=0 </pre> </div></div> <p>We are working to give to you the value of our highest group-quota limit.</p> <p>Thanks</p> <p>I created the attached file with all quota set for group, we don't use user quota but only group quota limit.</p> <p>Now the highest hard limit for Block is 734003200 and for Inode is 2000000.</p> <p>Regards</p> <p>Andrea Mattioli</p> <blockquote> <p>I created the attached file with all quota set for group, we don't use user quota but only group quota limit.</p> <p>Now the highest hard limit for Block is 734003200 and for Inode is 2000000.</p></blockquote> <p>such small limits should not trigger the overflow, maybe there are other reasons, or someone (or user app) was trying to set a very high limit but didn't success because of the defect.</p> <p>So,<br/> as workaround we could:<br/> 1. switch quotaoff<br/> 2. disable quota_switch_qs with lctl set_param lquota.*.quota_switch_qs=0<br/> 3. switch quotaon</p> <p>is it correct?</p> <p>which is the consequence to put to 0 the quota_switch_qs?</p> <p>thanks </p> <p>The consequence of setting quota_switch_qs=0 is that the qunit expanding/shrinking feature will be disabled, and quota unit （granularity) will always be default size (128M for block quota/5120 inodes for file quota).</p> <p>Without qunit shrinking, write will be more likely getting -EDQUOT when the total usage is still less than limit, because at least 1 qunit (128M) limit is allocated on each OST, even if the user doesn't have any objects on that OST.</p> <p>BTW: Do you know what kind of operations caused this problem? And if possible, could you provide the full stacktrace that Johann mentioned in comment #2? Thanks a lot.</p> <p>Hi, i am the client that are working with Supporto Lustre jnet2000 on this issue. To get the kernel dump we should enable the functionality of kexec / kdump on RHEL. We will do so whenever possible as this is a mission critical production env and we should be do a reboot for this. But agree that it is a useful thing to do.</p> <p>In any case, from the Lustre stack trace (under /tmp) I noticed that when the system crashes it has a load average of about 400 and seems to have some Lustre processes (kernel threads probably) hung and are not terminated, so the system crashes. These lustre processes are enumerating the secondary user groups via the standard POSIX API ( i am speaking of the default upcall /usr/sbin/l_getgroups), and we are using a central LDAP server as a POSIX USER/GROUP container (RFC2307bis). I believe that the bug is in the fact that these processes are not never terminated. Make sense ? </p> <p>In the meantine could be a useful workraround</p> <ul class="alternate" type="square"> <li>to define some timeout on the LDAP server for the ldap operation and connection ?</li> </ul> <ul class="alternate" type="square"> <li>Introduce a caching mechanism on SSSD, because the glibc nscd does not work very well (low cache hit) ?</li> </ul> <p>Thanks in advance</p> <p>We have upload the lustre dump when we open the issue. We don't have any kernel dump.</p> <p>The procedure to switch off the quota_switch_qs is it correct?

These lustre processes are enumerating the secondary user groups via the standard POSIX API ( i am speaking of the default upcall /usr/sbin/l_getgroups), and we are using a central LDAP server as a POSIX USER/GROUP container (RFC2307bis). I believe that the bug is in the fact that these processes are not never terminated. Make sense ? </p></blockquote> <p>Hmm, from the statcktrace provided in this ticket, seems the process is stuck in dquot_create_oqaq(), so it's very likely we ran into endless loop while expanding qunit in dquot_create_oqaq().</p> <p>Andrea\Elia</p> <p>So, is the immediate emergency dealt with and you are satisfied to know how to workaround this bug and that this bug will be fixed in a future version of Lustre?</p> <p>Peter</p> <p>Hi Peter,<br/> regard workaround, how can i set permanently this parameter set_param lquota.*.quota_switch_qs=0 ?<br/> Because after reboot this parameter returns in default value ( enabled ):</p> <p>Thanks </p> <p>Andrea Mattioli</p> <p>Hi, Andrea</p> <p>The quota_switch_qs can't be set by 'lctl conf_param', you might need to write a script to set it after mount lustre.</p> <p>After deploy workaround in environment "production" we found this error in Lustre server logs:</p> <p>Dec 21 17:11:36 osiride-lp-031 kernel: LustreError: 16687:0:(fsfilt-ldiskfs.c:2248:fsfilt_ldiskfs_dquot()) operate dquot before it's enabled!<br/> Dec 21 17:11:36 osiride-lp-031 kernel: LustreError: 16687:0:(quota_master.c:219:lustre_dqget()) can't read dquot from admin quotafile!

regards</p> <p>Andrea Mattioli</p> <p>I think it because the limit (256000) is too small for the MDT/OSTs. Without qunit shrinking, there is at least 1 qunit size block limit (128M) allocated for each OST and MDT, and it can't be revoked by master, if the total limit is too small for each OST/MDT having 1 qunit, then some of the OST/MDT will have 1 block limit at the end.</p> <p>Hi, Andrea</p> <p>You could run 'lfs quota -v -g testtest /home' to see if the MDT is having 1 block limit in such case. To resolve it without enableing qunit shrink, you have to set enough high limit (at least 1 qunit each OST/MDT). Thanks.</p> <p>Hi,<br/> this is the output of lfs quota -v -g testtest /home</p> <p><span class="error">&#91;root@osiride-lp-032 ~&#93;</span># lfs quota -v -g testtest /home<br/> Disk quotas for group testtest (gid 30942):<br/> Filesystem kbytes quota limit grace files quota limit grace<br/> /home 40 0 256000 - 10 0 500000 -<br/> home-MDT0000_UUID<br/> 16 - 1024 - 10 - 5120 -<br/> home-OST0000_UUID<br/> 4 - 1024 - - - - -<br/> home-OST0001_UUID<br/> 20 - 1024 - - - - -</p> <p>where i can see this value?</p> <p>Thanks</p> <p>Andrea Mattioli</p> <p>hm, that's strange, only 1MB was allocated to the slaves.<br/> Could you please run the following command on all the lustre servers?</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre># lctl get_param lquota.*.quota_*_sz lquota.*.quota_switch_qs </pre> </div></div> <p>hi this is the output.</p> <p><span class="error">&#91;root@osiride-lp-030 ~&#93;</span># lctl get_param lquota.<b>.quota_</b>_sz lquota.*.quota_switch_qs<br/> lquota.home-MDT0000.quota_btune_sz=67108850<br/> lquota.home-MDT0000.quota_bunit_sz=134217728<br/> lquota.home-MDT0000.quota_itune_sz=2560<br/> lquota.home-MDT0000.quota_iunit_sz=5120<br/> lquota.home-OST0000.quota_btune_sz=67108850<br/> lquota.home-OST0000.quota_bunit_sz=134217728<br/> lquota.home-OST0000.quota_itune_sz=2560<br/> lquota.home-OST0000.quota_iunit_sz=5120<br/> lquota.home-OST0001.quota_btune_sz=67108850<br/> lquota.home-OST0001.quota_bunit_sz=134217728<br/> lquota.home-OST0001.quota_itune_sz=2560<br/> lquota.home-OST0001.quota_iunit_sz=5120<br/> lquota.home-OST0002.quota_btune_sz=67108850<br/> lquota.home-OST0002.quota_bunit_sz=134217728<br/> lquota.home-OST0002.quota_itune_sz=2560<br/> lquota.home-OST0002.quota_iunit_sz=5120<br/> lquota.home-MDT0000.quota_switch_qs=changing qunit size is disabled</p> <p>Best Regards</p> <p>Andrea Mattioli</p> <p>All the parameters look sane on the server side.

Could you link the latest whamcloud lustre version that include the Niu Yawei patch for our quota bug?</p> <p>Could you close this issue?</p> <p>Thanks in advance.</p> <p>The first release that this patch is scheduled for inclusion in is Lustre 2.2, which is expected out in a couple of months time. I would suggest that you continue with the existing workaround for now. </p> <p>Hi Peter,<br/> so do you suggest to upgrade to 1.8.7-wc and not to the build #391 ?</p> <p>I would indeed suggest to upgrade to 1.8.7-wc and use the workaround for now.<br/> In fact, it is even worth trying to run w/o the workaround first, to see if the problem can be reproduced with a stock 1.8.7-wc release.</p> <p>We have not any choice to upgrade to another version of Lustre for the next 6 months... so we have to be sure to install a rock solid version!!!</p> <p>Please could you confirm the 1.8.7-wc version?</p> <p>Please close the issue. Thanks</p> <p>Yes Lustre 1.8.7-wc1 is the best option for you.</p> <p>Integrated in <span class="image-wrap" style=""><img src="http://build.whamcloud.com/images/16x16/blue.png" style="border: 0px
