Subject: NFS-ACL crashes sun server
I've got a network with a bunch of Sun machines (sol 8 in various stages of
patches), and a bunch of linux boxes.
The sun and linux disks are all accessible through the automounter.
I've recently upgraded one of the linux boxes to suse 8.2, which supports
ACLs over NFS .
The I did (as root, on the linux box)
cp -av /automount/sun/a/smalldirectory /automount/sun/b/nonexistentdestinationdir
(cp -av is a verbose cp -rp which also includes ACL information)
At the end of the copy action (when it was modifying/applying the acl info
to the copied files) the sun file server crashed, rebooted, came up, and as
soon as NFS was far enough back up to reprocess the outstanding requests
(and got to the ACL point) the sun server would crash again.
After about 15 minutes (and 4 crashes) I rebooted the linux box (as by then
had figured out that this might be the cause) and indeed the machine has not
crashed since.
I've now modified the linux boxes to not do ACL over NFS, but I am not happy
with this solution.
So my questions:
1) Is this a known problem ?
2) Is there a way to disable ACL on the NFS-Server (i.e. the Sun) side ?
The syslog shows:
