Is there anything beyond changing mkfs.lustre to not set the quota feature that would need to be done?</p> <p>The other issue is about enabling quota on such a filesystem. For upgraded filesystems, or new filesystems that do not have quota enabled by default, this would involve "tune2fs -O quota", and then running e2fsck? Is the distributed quota state on the master automatically rebuilt at this time? </p> LU-3396

Disable quota by default for 2.4

Bug Major Closed Won't Fix Andreas Dilger Andreas Dilger Fri, 24 May 2013 18:19:13 +0000 Fri, 21 Jun 2013 01:02:36 +0000 Fri, 21 Jun 2013 01:02:36 +0000 0 6 <p>Andreas, are you suggesting to disable accounting by default in ZFS as well?</p> <p>No, tune2fs is only for ldiskfs.</p> <p>Since 2.4.0 was shipped without this change, and we are instead pursuing a path to patch the quota code to fix the locking bottlenecks, I'm closing this bug as "Won't Fix".</p> Blocker LU-3305 Development Rank 1|hzvrun: Rank (Obsolete) 8408 Severity
