Troubleshooting
Problem
This technote explains why the error, [] db_VISTA database error -900 - no more space on file[], occurs when trying to reformat an IBM® Rational® ClearCase® VOB on AIX® without []Large File Enabled[].
Cause
Attempts to run cleartool reformatvob -load on AIX fails with the following error:
“18810000 pass 2 actions performed...
18815000 pass 2 actions performed...
18820000 pass 2 actions performed...
18825000 pass 2 actions performed...

The AIX filesystem is not configured to allow files larger than 2 Gigabytes (GB).
Review technote 1134066 for more details on Extended VOB Support.
Resolving The Problem
The filesystem must be upgraded to support large files, or files larger than 2 GB.
The command, lsfs –q <filesystem>, will show the parameters set on the filesystem.
Examples of two filesystems with and without large file support:
- /vobstore2 – set for large files:
# lsfs -q /vobstore2
Name Nodename Mount Pt VFS Size Options Auto Accounting
/dev/tempsk2lv -- /vobstore2 jfs 123731968 rw yes no
(lv size: 123731968, fs size: 123731968, frag size: 4096, nbpi: 131072, compress: no, bf: true, ag: 64)
- /vobstore – NOT set for large-files
# lsfs -q /vobstore
Name Nodename Mount Pt VFS Size Options Auto Accounting
/dev/tempsklv -- /vobstore jfs 123731968 rw no no
(lv size: 123731968, fs size: 123731968, frag size: 4096, nbpi: 4096, compress: no, bf: false, ag: 8)
Here is the command used to create, then build the filesystem on AIX:
The command string to create a filesystem on a previously existing Logical Volume (tempsk2lv in this example).
Note: The bf=true early in the command string.
/usr/sbin/crfs -v jfs -a bf=true -d'tempcc2lv' -m'/vobstore2' -A''`locale yesstr | awk -F: '{print $1}'`'' -p'rw' -t''`locale nostr | awk -F: '{print $1}'`'' -a nbpi='131072' -a ag='64'
