LVM Snapshots -broken ? Ever worked ?
I've upgraded my x86_64 4.2 box to the latest kernel 2.6.9.34 and tried
an lvm snapshot. It worked fine and I was able to mount the snapshot
etc. Now I cannot seem to remove the snapshot. If I try a 'lvremove'
it asks if I want to remove the 'active' snapshot, if I say yes it just
hangs and the box goes to 99% wait io, however the disk lights do not
come on during this. The

ssm list shows -
/dev/lvm_pool/lvol001
When I place /dev/lvm_pool/lvol001 into /etc/fstab the computer will
boot using kernel 514.
Kernel 862 still hangs/panics.

Best Practice to remove an ISCSI LVM from a system
Hi,
I'd like to know what would be the best way to remove an iscsi lvm
storage from a server. (removing all reference to that storage etc.)
The storage in question will be reset and reformated and used on a
different server; so no LVM export is needed.
Do I have to do lvremove ..., vgremove ..., pvremove ... and do an
iscsiadm -m node -T ... -p ... -u and
iscsiadm -m node -o delete -T ...

LVM2 snapshots and XEN = problem :(
Hello guys
Does anyone use lvm2 backends for domU storages ? I do and I wanted to
use lvm''s snapshot feature to make backups of domUs in background but I
got the following problem.
When I create a snapshot LV and copy data from it to backup storage it
works perfect.
Then I do umount and then lvremove. lvremove asks me if I really want to
remove the volume and then just hangs forever.

ssl and NameVirtualHost
I recently aquired a Verisign SSL certificate for my web server on
Centos 4, with apache 2.0.59 from centosplus.
It however doesn't seem to be working the way I've set it up,
browsers connect but are told the certiticate is not recognized.
Showing more info, the information looks correct.
I think it has probably to do with the fact that I'm using the
certificate on a virtual

Best way to take snapshots of iSCSI devices using Open-iSCSI + CentOS
Hi,
I want to take snapshots of a iSCSI devices from a target that hasn't
snapshot/cloning capabilities (it's a Infortrend A16E storage array).
What method are you using to make snapshots/clones of iSCSI targets
using Open-iSCSI + CentOS? What about using Open-iSCSI + LVM snapshots
system? For example:
- Take a LVM snapshot in the initiator with "lvcreate".
- Give read-only

can not lvcreate after lvm snapshot and "xm mem-set" and lvremove
I am not sure if it''s a xen bug or lvm bug, or just my bad hardware,
but here''s how to reproduce:
/dev/vg0/centos1 is lvm block used by a domainU, it''s 8G in size.
#lvcreate -L8192M -s -n snap1 vg0
#mount /dev/vg0/snap1 /mnt
do some copying files here
#umount /mnt
#lvremove /dev/vg0/snap1
not removed! it says can''t allocated memory
#xm mem-set 0 512
#lvremove

unable to write files bigger than 4GB over NFS
This may not be a CentOS problem, because I'm in a mixed environment.
But I put it out in case anybody has any thoughts.
I recently replaced a file server, which was on a Pentium III based
system running 32-bit CentOS 4.3, with an Opteron based system
running Fedora 4. The NFS clients are all CentOS 4.3, some are 32 bit
and some are 64 bit.
Since the replacement, when I try to write

Xen and LVM, bug at arch/x86/xen/mmu.c:1649?
I have a kernel BUG() most of the time when updating my LVM configuration.
I created a bug report on kernel linux-2.6 package as it looked related to
kernel; but searching through bug reports, it look like it's Xen related.
- No similar bug report about LVM crash for non-xen user
- Other Xen users have similar errors:

installing WIndows at end of disk
I have a functional CentOS system on which I need to install Windows
for dual boot. I can make some space available on a high partition.
Can WIndows be installed on partition 8 (starting with 1)? I have
always done it on the first partition.
Thanks,

firefox unable to load pkcs11 module
Hi Tony,
Have you solved this problem yet?I took another approach and used CACkey which supportsUS Government PIV cards including the CAC.? In my case I set it up on Linux Mint but there is an rpm version of CACKey for 32 or 64 bit Centos.Here is the process I went through.
- setup CAC card by following instructions on:

lvremove killed
hi,
My volume group is vg. Inside that i have around 10 lvm partitions
(each of 100GB).
When I try to remove partitions using
lvremove /dev/vg/lvm1
It acts like the machine freezes and after a long time the lvremove
process gets killed saying "Killed"
Whats wrong here.
I don't see anything interesting in /var/log/message
Thanks

Cannot remove lvs associated with deleted vm guests
At the beginning of January I encountered a problem where
several vm guests on a single host somehow managed to see
the the virtual disks assigned to other guests on the same
hosts. I was unable to resolve this situation and
shutdown the affected guests after creating new guest
instances and moving the services and data off the
corrupted guests.
I have since removed these guests via virt-manager
