...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 ... -p ... in order to achieve that? Or is there some more simple way? Thanks for any suggestion and best regards . G?tz -- G?tz Reinicke IT-Koordinator Tel. +49 7141 969 82 420 Fax +49 7141 969 55 420 E-Ma...

From: David H?rdeman <david@2gen.com> if a partition has been used as lvm2 and has not been cleared with pvremove, fstype would recognise the ext3 partition as lvm2. workaround that by detection lvm2 after ext3. Bonuspoint remove long fs list as this one just generates conflicts. Signed-off-by: David H?rdeman <david@2gen.com> Signed-off-by: maximilian attems <maks@sternwelten.at> diff --git a/u...

Hi, some time ago I removed some physical disks from a server and now I'm still getting dmesg messages like: sd 0:2:2:0: SCSI error: return code = 0x00040001 end_request: I/O error, dev sdc, sector 0 And all lvm tools still grumbel about that disks too: /dev/sdb: read failed after 0 of 4096 at 0: Eingabe-/Ausgabefehler /dev/sdb: read failed after 0 of 4096 at 1746969493504:

...with VMs. > Do you have some for straight-on-the-server, non-VM cases? I've used LVM on servers with hot-swap drives to migrate to new storage without downtime a number of times. Add new drives to the system, configure RAID (software or hardware), pvcreate, vgextend, pvmove, vgreduce, and pvremove (and maybe a lvextend and resize2fs/xfs_growfs). Never unmounted a filesystem, just some extra disk I/O. Even in cases where I had to shutdown or reboot a server to get drives added, moving data could take a long downtime, but with LVM I can live-migrate from place to place. LVM snapshots make it...

Hi all, I had centos 5.9 installed with one of its volumes (non-root) on LVM: ... /dev/vgapps/lvapps /opt/apps ext3 defaults 1 2 ... Then installed centos 6.4 on this servers but without exporting this volume (I wanted to reuse it). After that instead importing it I did: # pvcreate /dev/sddlmac # vgcreate vgapps /dev/sddlmac And then realised that I should have

Hi. I have a volume group (let's say) vg_data. It consists from /dev/sdd5 sdd6 sdd7 I added sdc5 Now I want to remove (free) sdd7 and you is to for RAID partition. What are the commands (ordered) I need to perform? I failed to find clear howto. vg-data has only one partition, total size is over 1TB, free space is about 500GB so

Hi All. Looking for some guidance/experience with LVM and pvmove. I have a LUN/PV being presented from a iscsi SAN. The LUN/PV is presented to 5 servers as a shared VG they all have LV's they use for data, they are all connected via iSCSI. As the SAN I am using is being replaced I need to move onto a new unit. My migration strategy at this time is to 1. Present a new LUN from the new SAN

I have set up a migration between two drives. fIrst I got Centos 5 working how I wanted on this drive, then set about copying it to another drive. The Centos files on both drives are in sub-partitions in an LVM partition on their respective drives. I first did a minimum install on the new drive and saved all those files to a separate directory. The LVM partititons and sub-partitions all

I''m a complete newbie at Xen, just getting started. I was happy to see that Ubuntu 11.10 includes Xen again, http://zulcss.wordpress.com/2011/09/04/xen-4-1-1-on-ubuntu/ So I installed ubuntu 11.10''s precompiled Xen, and started playing around with it. I''m not even trying to start another VM at the moment, just playing around with mounting block devices, and had trouble
