fsadm defrag with online JFS reports errors

[Haim Lichaa]

I have online JFS and I get the following message when performing defragmentation for the directory file.

fsadm: directory 452390 block 0 offset 4 has bad reclen 0
fsadm: directory 454758 block 0 offset 4 has bad reclen 0

fsadm: directory 2 block 0 offset 4 has bad reclen 0


Any body know what a "bad reclen" is? Where can I find more info?

Thanks

Hi Haim,

Bad reclen => Bad Record Length.
Points to an FS error in this filesystem.

I'd fun fsck -o full against this FS - unmounted. May need 2 passes. By default bad block relocation should be enabled & the data in that block will be moved to a good spot. Then you could run the defrag once more & all should be OK.

Rgds,
Jeff
