Quotas: Put quotacheck in a cron-job?

kenneho · 08-18-2009, 07:00 AM

Hi all.

I'm setting up quotas, and it seems to be working quite good. I read somewhere that it's recommended to run quotacheck on a regular basis, for example in a cron job. The problems is that the man page says that quotacheck prefer to mount the file system read only before performing the check. So how do other people do this (or maybe you simply don't)?

Regards,

Its not strictly necessary, but see 7.2.3 here: http://www.linuxtopia.org/online_boo...-managing.html
If you want to see how things (ie users) are doing, then its repquota (7.2.2 in above doc).

I see your point. But when the man page says this:

Quote:

It is strongly recommended to run quotacheck with quotas turned off for the filesystem. Otherwise, possible damage or loss to data in the quota files can result.

It is also unwise to run quotacheck on a live filesystem as actual usage may change during the scan. To prevent this, quotacheck tries to remount the filesystem read-only before starting the scan. After the scan is done it remounts the filesystem read-write. You can disable this with option -m. You can also make quotacheck ignore the failure to remount the filesystem read-only with option -M.

...I'm not sure who to trust - the red har manual or the man page. :/

I've decided to send a request to Red Hat support to clear up this issue. Keeping the quote from the man page in mind, it may be that Red Hat wish to clearify things in their documentation.

I'll report back here when I get a reply.

I've been in contact with Red Hat support, and they see that their documentation and the man page does not completely match. Until everything is cleared up I'm not running quotacheck on a mounted file system.
