Right now 3 of them are fine, and one is showing the same problem you described: mclane# ll /tank/home/pt/.zfs/ ls: snapshot: Bad file descriptor total 0 Note that zfs still thinks the snapshots are there: mclane# zfs list -r tank/home/pt NAME USED AVAIL REFER MOUNTPOINT tank/home/pt 454M 1.78T 262M /tank/home/pt tank/home/[EMAIL PROTECTED] 32.5M - 260M - tank/home/[EMAIL PROTECTED] 29.6M - 262M - tank/home/[EMAIL PROTECTED] 45.3K - 262M - tank/home/[EMAIL PROTECTED] 45.3K - 262M - tank/home/[EMAIL PROTECTED] 28.2M - 262M - tank/home/[EMAIL PROTECTED] 28.7M - 262M - tank/home/[EMAIL PROTECTED] 27.8M - 262M - tank/home/[EMAIL PROTECTED] 374K - 262M - tank/home/[EMAIL PROTECTED] 45.3K - 262M - tank/home/[EMAIL PROTECTED] 45.3K - 262M - tank/home/[EMAIL PROTECTED] 45.3K - 262M - tank/home/[EMAIL PROTECTED] 45.3K - 262M - tank/home/[EMAIL PROTECTED] 45.3K - 262M - tank/home/[EMAIL PROTECTED] 45.3K - 262M - tank/home/[EMAIL PROTECTED] 45.3K - 262M - tank/home/[EMAIL PROTECTED] 45.3K - 262M - tank/home/[EMAIL PROTECTED] 45.3K - 262M - I even do autoamtic incremental backups via send/receive. There are no errors (up to today) and the snapshots are accessible on the backup machine. I am a bit troubled by unaccessible snapshots. Does anyone else here have the same problem (or can even offer a solution)? cu Gerrit _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
