On Mon, 18 Jul 2011 12:38:22 +0200 Gerrit K=FChn <gerrit@pmp.uni-hannover.de> wrote about diskless booting with 8.2 regression?: 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 ser= ver: crw-r--r-- 1 root wheel 255, 0xffff00ff Jul 18 16:33 /tank/diskless/pt-f= e2/dev/console Strange enough, the Linux client still displays the correct values when usi= ng "ls -la", but it refuses to work properly. I tried creating new device nodes from the client side with mknod and I tri= ed getting correct ones from a backup, but they always end up being broken.= Even movong 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 s= tuff from zfs to ufs and dropping in a correct version of /dev on the ufs s= ide works just fine. However, it would be great if this could be fixed, because I do not have ma= ny ufs partitions left these days... cu Gerrit GK> Hi all, GK>=20 GK> I just updated my nfs/tftp server for diskless booting from 8.0-rel to GK> 8.2-stable.
