Problems with OnLine JFS

[Kevin Lamb]

Hi,

I am trying to reduce a filesystem with OnLineJFS version2 but am running into problems:

When I run the fsadm command I get the following error:
fsadm -F vxfs -b 307200 /systemdata
fsadm: cannot shrink /dev/vg02/rlvol2 - upgraded fs - inodes are currently in use.

I have ran a defrag (fsadm -d -D -e -E) and this reports as clean, I am able to unmount the directory without a problem.

I have ran lsof and there is no-one accessing the area.

Any ideas why this is failing?

Thx

Kev

The version of OFS you are using cannot cope with data on the extents you are trying to reduce. You need the later version of OJFS (3.3) which can do this. Running defrag was a good idea to try to free up the data on the extents but if it doesnt work youre out of luck.

Only option now is to create a new filesystem at the new size you want and cpio all the data over, then swap the entries in the fstab file.

Stefan,

Thanks for the info, I will try and organise an upgrade of the OJFS.

Thx
