[lustre-discuss] lustre project quotas

[Einar Næss Jensen]

Ok. I probably misunderstood this part:
Introduced in Lustre 2.10
Lustre filesystems formatted with a Lustre release prior to 2.10 can be still safely upgraded to release 2.10, but will not have project quota usage reporting functional until tune2fs -O project is run against all ldiskfs backend targets. This command sets the PROJECT feature flag in the superblock and runs e2fsck (as a result, the target must be offline). See Section 24.5, “ Quotas and Version Interoperability” for further important considerations.

I assumed this refered to project quotas being enabled as default when installing (not upgrading) version 2.10.x

also I was tricked by this output:
root at lustre-mds1 ~]# lctl get_param osd-*.*.quota_slave.info
osd-ldiskfs.LUSTRE1-MDT0000.quota_slave.info=
target name:    LUSTRE1-MDT0000
pool ID:        0
type:           md
quota enabled:  ugp
conn to master: setup
space acct:     ug
user uptodate:  glb[1],slv[1],reint[0]
group uptodate: glb[1],slv[1],reint[0]
project uptodate: glb[0],slv[0],reint[0]

which, I thought, showed that quota was enabled for users, groups and projects.

but apparantly not:
Filesystem features:      has_journal ext_attr dir_index filetype needs_recovery extent 64bit flex_bg sparse_super large_file huge_file uninit_bg dir_nlink quota


Thanks for clarification. I will schedule downtime and activate it.

please check 'dumpe2fs -h /dev/xxx | grep 'Filesystem features' if 'project' flag is enabled.
If not, you need to add it to all MDT/OSTs. e.g. tune2fs -O project /dev/xxx. described in Lustre manual in detail.

Thanks
