Error description
When attempting to access file elements in an IBM Rational ClearCase dynamic view from a Red Hat Enterprise Linux client, the following behavior has been observed if the VOB storage is mounted using Network File System version 4 (NFSv4). [user@rhel6 folder1]$ cat file cat: file: Not a directory This issue is accompanied by errors in the MVFS log (here with debug enabled): 2012-06-25T12:08:31-04:00 mvfs(0): Error: cleartext pname= /net/hangar18/vobstore/vob1.vbs/c/cdft/30/3b/e0b1050651c04baca08 13c814c4a56ff 2012-06-25T12:08:31-04:00 mvfs(0): Error: cleartext open failed view=rcs2 vob=/vobs/vob1 dbid=0x1d2 - Not a directory 2012-06-25T12:08:31-04:00 mvfs(0): DEBUG: openv: mnode=38004800 error=20 Error 20 is the Linux C error code for 'Not a directory' (ENOTDIR). This problem has only been observed on RHEL 6.x. Oracle Solaris and SuSE hosts are able to mount the same VOB storage using NFSv4, mount the same VOB and access the same file element without issue. Steps to reproduce the issue: 1) Mount VOB storage from a Solaris VOB server NFS share using NFSv4. 2) Mount the VOB, set to a view and cd into the VOB. 3) Cat a file element. WORKAROUND: Mount the VOB storage using NFS version 3 (NFSv3) or use a snapshot view.
