Attempt to access beyond end of device
This is what I have:
RedHat AS 5.1 64 bit Qlogic HBAs (failover mode) EVA storage LVM VG INFORMATION: --- Volume group --- VG Name myvg System ID Format lvm2 Metadata Areas 24 Metadata Sequence No 8 VG Access read/write VG Status resizable MAX LV 0 Cur LV 3 Open LV 3 Max PV 0 Cur PV 24 Act PV 24 VG Size 383.91 GB PE Size 4.00 MB Total PE 98280 Alloc PE / Size 97280 / 380.00 GB Free PE / Size 1000 / 3.91 GB VG UUID XwE1BI-BNn9-LfPl-9XKW-M0y2-t7bb-5mMHtN LV INFORMATION: --- Logical volume --- LV Name /dev/myvg/mylv VG Name ora01wvg LV UUID cxHbI5-CgqR-AMbp-GgQv-QqKd-Mfdw-RXsAvP LV Write Access read/write LV Status available # open 1 LV Size 185.00 GB Current LE 47360 Segments 13 Allocation inherit Read ahead sectors 0 Block device 253:37 Filesystem = ext3 I got the following message in my messages file. I have a couple of questions surrounding it. * Is it possible to prevent RedHat from mounting in read-only when it encounters a filesystem problem? I would rather it just unmount the filesystem than to mount read-only. * Is this a storage/LVM/OS issue?

As to a file system being mounted read-only, you can try to "re-mount" it read-write in this fashion:
mount -o remount,rw /your-directory-name-here As to the potential LVM related issues, you should make sure that you have logical volumes, formatted to the same size as you've told the LVM they are ( in the sense of resize2fs ) , mounted in the right place and such. For example on my system, in what you've shown us, if the logical volume you're showing us in what you've posted, was meant to be a part of the volume you've shown us, the VG name field for the logical volume would be the same as the VG name field in the volume group information. Are we missing some output here? |
