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



i'll try with 2.4.9 and with 2.4.9ac5
how do you think should i do it with LVM-1.0.1rc1 or rc2
i think i should try with rc1 to find whether it comes from the xfs kernel changes, as i'm currently using rc1

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

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


It could just be lucky that JFS works, depending on access patterns.


and the one with ext2 :

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

Writing inode tables: Segmentation fault


Then it is definitely not anything to do with the filesystem itself (although it may be with the XFS patch). Try a kernel without the XFS patch and see if this makes a difference. Maybe it is a bad interaction between XFS, RAID, LVM?
