VFS: No free dquots

[Benjamin de los Angeles Jr.]

Hello,

I got this error message "VFS: No free dquots, contact
[EMAIL PROTECTED]" when I extracted a 2GB tar file, an archive of
mailboxes to a RAID-1 device.  How do I increase the number of dquots?
I used kernel 2.2.1 and 2.2.2, but still has this error.
