Can you double check that those devices exist? "/dev/disk/by-vdev" "/dev/mapper" "/dev/disk/by-partlabel" "/dev/disk/by-partuuid" "/dev/disk/by-label" "/dev/disk/by-uuid" "/dev/disk/by-id" "/dev/disk/by-path" "/dev" |

here are the paths for the drives on this oss server, the strange thing is that i was able to add lrwxrwxrwx 1 root root 8 Aug 9 20:33 /dev/mapper/35000c500837f2a77 -> ../dm-92 created the zpools on the other server: OSS1-A210 obd]# zpool list zpool status NAME STATE READ WRITE CKSUM errors: No known data errors pool: ost5 NAME STATE READ WRITE CKSUM errors: No known data errors pool: ost6 NAME STATE READ WRITE CKSUM errors: No known data errors pool: ost7 NAME STATE READ WRITE CKSUM errors: No known data errors pool: ost8 NAME STATE READ WRITE CKSUM errors: No known data errors thanks, |

The mpath's listed in the create, aren't listed in /dev/mapper/. Maybe the LUs aren't mapped to this server? |
| Comment by Abe [ 11/Aug/17 ] |

it looks like it is mapped: lrwxrwxrwx 1 root root 7 Aug 11 13:42 /dev/mapper/35000c5008355e01f -> ../dm-4 |

Here are the following instructions for ftp upload: Sometimes the diagnostic data collected as part of Lustre troubleshooting is too large to be attached to a JIRA ticket. For these cases, HPDD provides an anonymous write-only FTP upload service. In order to use this service, you'll need an FTP client (e.g. ncftp, ftp, etc.) and a JIRA issue. Use the 'uploads' directory and create a new subdirectory using your Jira issue as a name. $ ls -lh total 333M -rw-r--r-- 1 mjmac mjmac 98M Feb 23 17:36 mds-debug -rw-r--r-- 1 mjmac mjmac 118M Feb 23 17:37 oss-00-debug -rw-r--r-- 1 mjmac mjmac 118M Feb 23 17:37 oss-01-debug $ ncftp ftp.hpdd.intel.com NcFTP 3.2.2 (Sep 04, 2008) by Mike Gleason (http://www.NcFTP.com/contact/).

Hi Nathaniel, The problem went away after i rebooted the server, however still like to know [root@OSS1-A212 tmp]# ncftp ftp.hpdd.intel.com Copyright (c) 1992-2011 by Mike Gleason. Connecting to ftp.hpdd.intel.com... thanks, |

Looking at the log, it looks like you had ZFS 0.6.5.9 installed then upgraded to 0.7.0, but the old modules weren't unloaded prior to upgrade, so I think that is where the issue lay, and why a reboot fixed it. |
