From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050322 Firefox/1.0.2 Red Hat/1.0.2-1.4.1 Description of problem: I get repeated superblock errors when attempting to mount netapp exported filesystem via nfs4. Eventually, the connection will work (after multiple attempts over a prolonged time period) Version-Release number of selected component (if applicable): nfs-utils-1.0.6-46 How reproducible: Always Steps to Reproduce: 1. boot system, attempt nfs4 mount 2. keep trying and trying.. 3. eventually it will work.. Actual Results: received superblock error Expected Results: should mount (as it eventually does) Additional info: I will be uploading a strace output shortly.. I read there's an updated nfsutils out there somewhere.. will it be released for RHEL4 shortly?
Created attachment 112390 [details] strace output of failed nfsv4 mount
I believe this is the problem.... mount("NFSSERVER:/vol/vol0/home/accounts/user", "/mnt/remote", "nfs4", 0xc0ed0000, 0x805c3e0) = -1 EINVAL (Invalid argument) what are your arguments to the mount command and how are the filesystems exported on the server?
Putting in NEEDINFO awaiting feedback requested in comment 2.
I thought I had posted an update yesterday.. odd.. regardless, i'm mounting a share exported on a netapp with kerberos 4 enabled. I mount with the following command mount -t nfs4 netapp:/export /mnt/point sometimes it works, sometimes it doesn't.. it's not 100% failure, but when it fails, I always get the superblock error..
Would it be possible to post a bzip2-ed ethereal trace (i.e. tethereal -w /tmp/data.pcap) of this failure? FYI.. most of the time EINVAL errors translate to export issues.
