Description Tim Clymo 2001-03-12 21:15:21 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.2-0.1.20 i686)

Wolverine system with latest rawhide kernel (2.4.2-0.1.19).
LVM tools updated to beta5 from SRPM at people.redhat.com/laroche
Kernel built with LVM patches from above SRPM - also changed to have
builtin - not modular - support for raid1 and reiserfs (and turn off
reiserfs extensive checking). All other options as for
LVM - 1VG containing 1PV (8Gb RAID-1 partition md1)

Create new lvol (128Mb) and mkfs -t reiserfs -v 2 /dev/vgname/newlvol.
Mount it, and then unmount it. Now mkfs /dev/vgname/newlvol. Trying to
mount it again gives error "mount: wrong fs type, bad option, bad
superblock on /dev/vgname/newlvol,
       or too many mounted file systems"

Dmesg reports "EXT2-fs: blocksize too small for device."

A reboot will enable the device to be mounted

This doesn't happen if the device is a straight single disk partition,
although I haven't tried with a standard md device with lvm out of the loop

It does happen with LVM using a disk partition as a PV instead of a raid1
md device, indicating that this is probably an LVM issue

Reproducible: Always
Steps to Reproduce:
1. See description

LVM will be disabled in the final version.
