Re: [linux-lvm] PBs with LVM over software RAID



hi
it works with IMB's JFS
when i try mkfs -t reiserfs -f /dev/myData/SRC it segfaults :

[root svetljo mnt]# mkfs -t reiserfs -f /dev/myData/SRC
mkreiserfs, 2001 - reiserfsprogs 3.x.0j
===================================================================
LEAF NODE (8211) contains level=1, nr_items=2, free_space=3932 rdkey
-------------------------------------------------------------------------------

-------------------------------------------------------------------------------
Segmentation fault


isn't that a bit strange that reiserfs and xfs doesn't handle it, but jfs does

and the one with ext2 :

[root svetljo mnt]# mkfs -t ext2 /dev/myData/SRC

Writing inode tables: Segmentation fault

i realy don't like that

OK, so the oops is inside the RAID layer, but it may be that it is being fed bogus data from a higher layer. Even so, it should not oops in this case. Since XFS changes a lot of the kernel code, I would either suggest asking the XFS folks to look at this oops, or maybe on the MD RAID mailing list, as they will know more about it.

Cheers, Andreas
