Hi, it might help to disable quota using tune2fs and re-enable it again on the ext2 level on all devices, see LU-3861. (BTW you don't need the e2fsprogs mentioned in the bug, there was an official release last year in September).
You have to stop lustre for the tune2fs run and it takes some time, because this triggers a quota check in the background (which does not produce any output on the screen). best regards, Martin On 07/28/2015 09:44 AM, Torsten Harenberg wrote: > a further observation: > > a user deleted a ~100MB file: > > before. > > [root@wnfg001 lustre]# lfs quota -u sandhoff /lustre > Disk quotas for user sandhoff (uid 11206): > Filesystem kbytes quota limit grace files quota limit > grace > /lustre 811480188 1811480200 2811480200 - 61077 0 > 0 - > > after: > > [root@wnfg001 lustre]# lfs quota -u sandhoff /lustre > Disk quotas for user sandhoff (uid 11206): > Filesystem kbytes quota limit grace files quota limit > grace > /lustre 811480188 1811480200 2811480200 - 61076 0 > 0 - > [root@wnfg001 lustre]# > > so #files decreased by 1, but not the #kbytes. > > Furthermore, the lfs quota command is pretty slow: > > [root@wnfg001 lustre]# time lfs quota -u sandhoff /lustre > Disk quotas for user sandhoff (uid 11206): > Filesystem kbytes quota limit grace files quota limit > grace > /lustre 811480188 1811480200 2811480200 - 61076 0 > 0 - > > real 0m2.441s > user 0m0.001s > sys 0m0.004s > [root@wnfg001 lustre]# > > although the system is not overloaded. > > Couldn't find anything useful in dmesg: > > [root@lustre2 ~]# dmesg | grep quota > VFS: Disk quotas dquot_6.5.2 > LDISKFS-fs (dm-1): mounted filesystem with ordered data mode. quota=on. > Opts: > [root@lustre2 ~]# > > [root@lustre3 ~]# dmesg | grep quota > VFS: Disk quotas dquot_6.5.2 > LDISKFS-fs (dm-6): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-4): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-7): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-1): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-9): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-13): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-12): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-10): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-6): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-4): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-7): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-1): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-9): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-13): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-12): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-10): mounted filesystem with ordered data mode. quota=on. > Opts: > [root@lustre3 ~]# > > [root@lustre4 ~]# dmesg | grep quota > VFS: Disk quotas dquot_6.5.2 > LDISKFS-fs (dm-1): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-8): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-13): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-0): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-3): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-14): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-2): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-1): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-8): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-13): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-0): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-3): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-14): mounted filesystem with ordered data mode. quota=on. > Opts: > LDISKFS-fs (dm-2): mounted filesystem with ordered data mode. quota=on. > Opts: > [root@lustre4 ~]# > > Thanks for any hint! > > Best regards > > Torsten >
