Description of problem: upgrading to latest kernel (2.6.18-308.1.1.el5) broke access to .snapshot directories mounted from a network appliance filer. Downgrading to previous version (2.6.18-274.18.1.el5) fixes the issue. Version-Release number of selected component (if applicable): kernel-2.6.18-308.1.1.el5 How reproducible: Always Steps to Reproduce: 1.boot into 2.6.18-308.1.1.el5 2.ls -a mountpoint/.snapshot 3.cd mountpoint/.snapshot Actual results: [thomas@admin: ~] $ uname -r 2.6.18-308.1.1.el5 [thomas@admin: ~] $ ls -ld /mnt/storage/.snapshot drwxrwxrwx 42 root root 4096 Apr 13 12:07 /mnt/storage/.snapshot [thomas@admin: ~] $ cd /mnt/storage/.snapshot -bash: cd: /mnt/storage/.snapshot: Not a directory Expected results: [thomas@admin: ~] $ uname -r 2.6.18-274.18.1.el5 [thomas@admin: ~] $ ls -ld /mnt/storage/.snapshot drwxrwxrwx 42 root root 4096 Apr 13 13:09 /mnt/storage/.snapshot [thomas@admin: ~] $ ls -l /mnt/storage/.snapshot total 160 drwxr-xr-x 19 root root 4096 Mar 7 00:04 sv_daily.0 drwxr-xr-x 19 root root 4096 Mar 7 00:04 sv_daily.1 drwxr-xr-x 19 root root 4096 Mar 7 00:04 sv_daily.10 drwxr-xr-x 19 root root 4096 Mar 7 00:04 sv_daily.11 ...

I am experiencing the same problem with kernel-2.6.18-308.1.1.el5 except I am serving them from a RHEL nfs server using NFS4 and tcp. Some of the nfs mounts work but most of them do not. Here are how some of the exports are setup. /export X.X.X.X/24(rw,fsid=0,no_subtree_check) /export/home X.X.X.X/24(rw,fsid=____,no_subtree_check,nohide,secure) /export/dir1/dir2/dir3/filestore X.X.X.X(rw,fsid=____,no_subtree_check,nohide) Mounting nfsserver:/home/<username> works fine using autofs We have nfsserver:/export/dir1 mounted on the client and trying to access exports under this mount point causes the "Not a directory" error on the client.
