>Description: Copied from my email on freebsd-stable: I guess I found the root of all evil now: device nodes on zfs! This is how a linux /dev/console looked on the 8.0-FreeBSD server on zfsv15: crw------- 1 root wheel 5, 1 Oct 28 2010 /tank/diskless/gco-fe2/dev/console Now, after updating to FreeBSD-8.2 and zfsv28 it looks like this on the server: crw-r--r-- 1 root wheel 255, 0xffff00ff Jul 18 16:33 /tank/diskless/pt-fe2/dev/console Strange enough, the Linux client still displays the correct values when using "ls -la", but it refuses to work properly. I tried creating new device nodes from the client side with mknod and I tried getting correct ones from a backup, but they always end up being broken. Even moving the directories over to a ufs volume leaves them unusable: crw-r--r-- 1 root wheel 0, 0 Jul 18 16:33 /tmp/console Luckily, I am back into business now with my machines, because moving the stuff from zfs to ufs and dropping in a correct version of /dev on the ufs side works just fine. However, it would be great if this could be fixed, because I do not have many ufs partitions left these days... >How-To-Repeat: Upgrade filesystems containing device nodes (Linux diskless client in this case) to zfsv28 on FreeBSD 8.2-stable. >Fix: >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
