Hi... I have had a problem when I am going to detach one specific LVM partitions of Xen, so I have been trying xm destroy <domain>, lvchange -an <lvm_partition>, lvremove -f.... So I haven''t had sucess. I restarted the server with init 1 yet and nothing... I have seem two specific process started xenwatch and xenbus, but I am not sure if this processes have some action over

hello all, Hoping for some help on copying Logical Volumes. I would like to copy an existing LV to a newly formed LV. I don't want to do a snapshot of an existing LV. Only way I've seen is to mount the to LV and: mount /dev/vg00/lv00 /mnt/orig mount /dev/vg00/lv01 /mnt/copy cd /mnt/orig tar cf - ./ |(cd /mnt/copy; tar xf - ) Is there a LV tool to do this? Or an option used with

Hi, I want to rename some volume groups and logical volumes. I was not surprised when it would not let me rename active volumes. So I booted up the system using the CentOS 5.5 LiveCD, but the LiveCD makes the logical volumes browsable using Nautilus, so they are still active and I can't rename them. Tried: /usr/sbin/lvchange -a n VolGroup00/LogVol00 but it still says: LV

Hello, this is my first time posting on this mailing list. I wanted to suggest a addition to the qemu hook. I will explain it through my own use case. I use a shared LVM storage as a volume pool between my nodes. I use lvmlockd in sanlock mode to protect both LVM metadata corruption and concurrent volume mounting. When I run a VM on a node, I activate the desired LV with exclusive lock

I could launch `lvchange -asy` on the source host manually, but the aim of hooks is to automatically execute such commands and avoid human errors.

I know how to change the UUID of Physical Volumes and Volume Groups, but when I try to do the same for a Logical Volume, lvchange complains that "--uuid" is not an option. Here is how I've been changing the others (note that "--uuid" does not appear in the man pages for pvchange and vgchange for lvm2-2.02.26-3.el5): pvchange --uuid {pv dev} vgchange --uuid {vg name} Any

Did a search for LVM at the CentOS bugzilla. Nothing seems to match this scenario. If no one contradicts me, I'll also post this in the bug reporting system. Wanted to a) get confirmation, if possible before bugging it and b) warn other souls that may be adventurous too! Summary: failings in LVM and kernel(?) seem to make a "freeze" possible. 1) Lvchange --permission=r seems to

Hi all. I have currently a server: cat /etc/redhat-release CentOS release 5.7 (Final) uname -a Linux host.domain.com 2.6.18-274.18.1.el5 #1 SMP Thu Feb 9 12:45:44 EST 2012 x86_64 x86_64 x86_64 GNU/Linux I have there a filesystem mounted: /dev/vg0/paczki /home/paczki-workdir ext4 defaults,noatime 0 0 on which df gives strange output: LANG=C df -h

I'm pulling my hair out trying to setup a mirrored logical volume. lvconvert tells me I don't have enough free space, even though I have hundreds of gigabytes free on both physical volumes. Command: lvconvert -m1 /dev/vg1/iscsi_deeds_data Insufficient suitable allocatable extents for logical volume : 10240 more required Any ideas? Thanks!, Gordon Here's the output from the

Hello, I have a weird problem after adding new PV do LMV volume group. It seems the error comes out only during boot time. Please read the story. I have couple of 1U machines. They all have two, four or more Fujitsu-Siemens SAS 2,5" disks, which are bounded in Raid1 pairs with Linux mdadm. First pair of disks has always two arrays (md0, md1). Small md0 is used for booting and the rest - md1

Hi Stefan, I think what you propose will work, though you should test it thoroughly. I think more generally, "the GlusterFS way" would be to use 2-way replication instead of a distributed volume; then you can lose one of your servers without outage. And re-synchronize when it comes back up. Chances are if you weren't using the SAN volumes; you could have purchased two servers

Dear all, I'm rather new to glusterfs but have some experience running lager lustre and beegfs installations. These filesystems provide active/active failover. Now, I discovered that I can also do this in glusterfs, although I didn't find detailed documentation about it. (I'm using glusterfs 3.10.8) So my question is: can I really use glusterfs to do failover in the way described

Hi Alex, Thank you for the quick reply! Yes, I'm aware that using ?plain? hardware with replication is more what GlusterFS is for. I cannot talk about prices where in detail, but for me, it evens more or less out. Moreover, I have more SAN that I'd rather re-use (because of Lustre) than buy new hardware. I'll test more to understand what precisely "replace-brick"

'--no-degraded' flag in the first mdadm call inhibits the startup of array unless all expected drives are present. This will prevent starting arrays in degraded state. Second mdadm call (after LVM is scanned) will scan unused yet devices and make an attempt to run all found arrays even they are in degraded state. Two new tests are added. This fixes rhbz1527852. Here is boot-benchmark

I am using RHEL 5.1 with custom kernel. I have a LV I am trying to remove and its keep complaining its open. I have unmounted the filesystem, lsof shows nothing, fuser shows nothing. I am certain a reboot will fix it, but I don't know why this occurs. Can anyone shed some light on this? Are there some other LVM hacks I can use for this? TIA
