[Lustre-discuss] Lustre quotas using a journaled quota

[Ms. Megan Larko]

Howdy!

How can I tell if an existing Lustre file system (either 1.6.7.2 or
1.8.3) is using a journaled quota system?

I have been reading that if a Lustre file system is set-up using
journaled quotas then the command "lfs quotacheck -ug /mnt/lustre"
could be avoided following an unclean (crash) unmount of Lustre.  Is
this true for 1.8.x?   Is journaling the quota information analogous
to providing an external journal for a file system in that I need only
to specify the flag and point to which the quota journal should be
written?  What are the downsides to an external journal for quota
information in Lustre?

Note:  My questions stem from reading the Lustre 1.8 Operations Manual
section 9.1.1

TIA!
