Hi there,
Well.. I didn't find a way to strace imap. If I well understood, the faulty
IMAP is launched by dovecot from or after a succesfull imap-login process. I
have executed manually '/usr/libexec/dovecot/imap -u eric' and typed
getquotaroot "INBOX" which didn't reproduce the error seen in the dovecot logs
and reported the correct quota.
Any idea how to find the imap command generating the error
imap(eric)<3085></M5VXfCBwJejrKVa>: Error: Failed to get quota resource
STORAGE: quota-fs: quotactl(Q_GETQUOTA, /dev/vda1) failed: No such file or
directory
Thanks and regards,
