I'm trying to get XFS working on LVM. I'm almost there, but I'm hitting
a problem (or two). Here's the set up
A newly installed Redhat 7.1 system
A fresh (today) XFS kernel tree from CVS
A fresh copy ov LVM
If I take the machine down to single user mode, and fdisk it to create a
single large partition on a disk. I can create the pv, and the vg with
no problem. Then I create multiple logical volumes on the large vg. This
also works fine. The problems start when I try to create XFS filesystems
on the logical volumes.
The first one or two might create ok, and mount up, then it just falls
apart, with errors on block counts, and block access, etc. (I didn't
capture the exact error messages, but I'm hoping that someone here has
encountered this, and knows what it is. Two messages I did capture were:
lvm -- lvm_blk_ioctl: unknown command 0x126e
mkfs.xfs: warning - cannot set blocksize on block device
/dev/datavg/biglv: Invalid Argument.
Has anyone else seen this, and how do I cure it?
Thanks in advance!
