Hello Andreas, Thank you for your response. This is exactly what we do on one of our file systems. We are not able to do this on this other file system for the following reason: [r...@iliadaccess04 ~]# lfs quotacheck -ug /n/scratch quotacheck failed: Input/output error [r...@iliadaccess04 ~]# tail /var/log/messages Apr 6 10:27:58 iliadaccess04 kernel: LustreError: 24683:0:(quota_check.c:246:lov_quota_check()) lov idx 34 inactive [r...@iliadaccess04 ~]# lctl dl ... 43 UP mgc mgc10.242.62....@tcp 1144636d-657d-d672-cb82-b7ed47117624 5 44 UP lov aegalfs-clilov-ffff81042de30c00 6102ae5d-0599-15dd-7bfc-3d971d20b099 4 45 UP mdc aegalfs-MDT0000-mdc-ffff81042de30c00 6102ae5d-0599-15dd-7bfc-3d971d20b099 5 46 UP osc aegalfs-OST002a-osc-ffff81042de30c00 6102ae5d-0599-15dd-7bfc-3d971d20b099 5 47 UP osc aegalfs-OST0000-osc-ffff81042de30c00 6102ae5d-0599-15dd-7bfc-3d971d20b099 5 ... 80 UP osc aegalfs-OST0021-osc-ffff81042de30c00 6102ae5d-0599-15dd-7bfc-3d971d20b099 5
For some reason when the file system was constructed that one OST was built with a peculiar ID. And as far as we know, once an OST, always an OST. And we figured that since this was a live file system, we were stuck with it being for ever without quota. If there is a way around this, that would be ideal! Thanks. Suvendra.
