Hi there,
Initial experiments suggest that the disable/off/remove commands are not
available when a drive is mounted without quota accounting switched on.
So it looks like we won't be able to use them.
Is there another way to clear all the old quota information from a drive?
rgds,

Hi there,
We've got a moderately large disk (~2TB) into an inconsistent state,
such that it's going to want a quotacheck the next time we mount it
(it's currently mounted with quota accounting inactive). Our tests
suggest this is going to take several hours, and cause an outage we
can't afford.
We're wondering whether there's a 'nuke the site from orbit' option
that will let us avoid it. The plan would be to:
- switch off quotas and delete them completely, using the commands:
-- disable
-- off
-- remove
- remount the drive with -o prjquota, hoping that there will not be a
quotacheck, because we've deleted all the old quota data
- run a script gradually restore all the quotas, one by one and in
good time, from our own external backups (we've got the quotas in a
database basically).
So the questions are:
- is there a way to remove all quota information from a mounted drive?
(the current mount status seems to be that it tried to mount it with
-o prjquota but that quota accounting is *not* active)
- will it work and let us remount the drive with -o prjquota without
causing a quotacheck?
Answers on a postcard, received with the utmost gratitude.
