Description

We have had a catastrophic failure of one of our lustre filesystems. Not sure exactly cause, but in our current state running lfsck on it gives TONS of errors like:
Failed to find fid [0xc900ec:0xd7e33ef4:0x0]: DB_NOTFOUND: No matching key/data pair found

And when we run a find on various users' directories, we find many "No such file" errors:
find: ./mrtoeppe/CFD_run_archive/Turbine2DecDet/mcfd_tec.bin.830: No such file or directory which shows up like:

?--------- ? ? ? ? ? mcfd_tec.bin.660
?--------- ? ? ? ? ? mcfd_tec.bin.670
?--------- ? ? ? ? ? mcfd_tec.bin.680

Issue Links

• Trackbacks: Lustre 1.8.x known issues tracker While testing against Lustre b18 branch, we would hit known bugs which were already reported in Lustre Bugzilla https://bugzilla.lustre.org/. In order to move away from relying on Bugzilla, we would create a JIRA
