(Kernel 2.4.29 - jfsutils 1.1.7)

Hi All!

We have also in the last days a lvm-disk extended and than

mount -o remount,resize

It looks like no prob. But after about 20 hours we got this:

Mar  9 17:59:42 ibm235 kernel: ERROR: (device lvm(58,0)): dtReadFirst:
btstack overrun
Mar  9 17:59:42 ibm235 kernel: btstack dump:

Mar  9 17:59:42 ibm235 kernel: bn = c0149df2000003e8, index = 1000

and the fs mounted readonly.

An fsck on the readonly-mounted fs tells me:

Filesystem is clean.

But after remount rw some errors occured again.

At next we unmount the dev an run fsck on unmounted fs -> some errors
repaired an after mount rw -> no prob anymore..
