Hi, I'm going to be involved in a migration of SAN islands to one big SAN. I've not worked with SANs before and I'm not sure how to approach this. I suspect the disk devices on the HP servers are going to change, when the EVA's and servers are plugged into this new Cisco 9509 switch.

Hello,
I have logical volume group of 50GB, in which I have 2 logical volumes, LogVol01 and LogVol02, both are of 10GB.
If I extend LogVol01 further by 10GB, then it keeps the extended copy after logical volume 2. I want to know where it keeps this information

Does anyone have any simple methods for moving a current logical volume from one volume group to another? I do not wish to move the data from one physical volume to another. Basically, I want to "relink" the logical volume to exist in a different volume group. Any ideas? (2 Replies)

blkdeactivate
BLKDEACTIVATE(8)BLKDEACTIVATE(8)NAME
blkdeactivate - utility to deactivate block devices
SYNOPSIS
blkdeactivate [options] [device...]
DESCRIPTION
blkdeactivate utility deactivates block devices. If a device is mounted, the utility can unmount it automatically before trying to deacti-
vate. The utility currently supports device-mapper devices, including LVM volumes. LVM volumes are handled directly using the lvm command.
Other device-mapper based devices are handled using the dmsetup command.
OPTIONS -e, --errors
Show errors reported from tools called by blkdeactivate. Without this option, any error messages from these external tools are sup-
pressed and the blkdeactivate itself provides only a summary message about device being skipped or not.
-h, --help
Display the help text.
-u, --umount
Unmount a mounted device before trying to deactivate it. Without this option used, a device that is mounted is not deactivated.
-v, --verbose
Run in verbose mode.
-d, --dmoption dm_options
Comma separated list of device-mapper specific options.
-l, --lvmoption lvm_options
Comma separated list of LVM specific options.
DM_OPTIONS
retry Retry removal several times in case of failure.
force Force device removal. See dmsetup(8) for more information.
LVM_OPTIONS
retry Retry removal several times in case of failure.
wholevg
Deactivate the whole LVM Volume Group when processing a Logical Volume. Deactivating Volume Group as a whole takes less time than
deactivating each Logical Volume separately.
EXAMPLES
Deactivate all supported block devices found in the system. If a device is mounted, skip its deactivation.
blkdeactivate
Deactivate all supported block devices found in the system. If a device is mounted, unmount it first if possible.
blkdeactivate -u
Deactivate supplied device together with all its holders. If any of the devices processed is mounted, unmount it first if possible.
blkdeactivate -u /dev/vg/lvol0
Deactivate all supported block devices found in the system. Retry deactivation of device-mapper devices in case the deactivation fails.
Deactivate the whole Volume Group at once when processing an LVM Logical Volume.
blkdeactivate -u -d retry -l wholevg
Deactivate all supported block devices found in the system. Retry deactivation of device-mapper devices in case the deactivation fails and
force removal.
blkdeactivate -d force,retry
