Hello,
I'm using a Sybase utility that backs up entire databases to a CIFS share on my FreeNAS 9.2.1.5 server every night. The database file sizes range between 60 GB and 500 GB, and I usually have about 4 servers backing up to it at the same time.
About once a week, the backup fails in the middle of it, outputting filesystem errors 'Bad file number' (EBADF) or 'Invalid argument' (EINVAL). From what I understand, these errors are coming the OS filesystem layer, not from the backup utility.
Has anyone else had EBADF or EINVAL errors over CIFS shares?
There doesn't seem to be anything else logged on either the FreeNAS server or Windows servers. The backups are being written to the 'mybackups' share.
Output of testparm:
