Hi,
On a fairly busy mail server hosting about 1000 cyrus mailboxes (each
message is stored as a separate file), we are observing ENOSPC errors
from the cyrus pop/imap daemons when attempting to create (tiny)
files. e.g.
Oct 8 12:18:49 xxx cyrus/pop3[14119]: IOERROR: creating
/user/imap/proc/14119: No space left on device
Oct 8 12:18:49 xxx cyrus/lmtpunix[14361]: IOERROR: creating quota
file /user/imap/quota/m/user.xx.NEW: No space left on device
Oct 8 12:18:49 xxx cyrus/imap[12804]: IOERROR: creating quota file
/user/imap/quota/d/user.xxx.NEW: No space left on device
The filesystem appears to have plenty of space available:
# df -i /user
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/sdb1 102294688 10201313 92093375 10% /user
# df /user
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sdb1 213014148 190023408 22990740 90% /user
Any ideas for how can we go about debugging where ENOSPC is coming
from? Unfortunately it's running a vintage 2.6.24 kernel (Ubuntu 8.04)
- we're trying to get it upgraded to 10.04 (2.6.32)
Thanks, James
