Shared Logical Volume betweem two node on concurrent mode
Hello All;
I'm very new in AIX
I'm still confused with a scenario on our client infrastructure. They have two serveur bd1 and bd2 connected directly on a IBM V3700 Storage.
They want to create a file system on bd1 and share this one with bd2 so when they will create a file on the mount point of the shared file system on db1 they can access it on db2...
It's my first time to work on AIX.... I have no documentation to guide me doing what our client needs.
If someone can explain to me a way or give me a step by step link where i can do it easily i will be very happy.
Thank you in advance.

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)

Hello everyone,
I just read that while creating a logical volume(LV) we can choose the region of the physical volume (PV) in which the LV should be created.
When I say region I mean: outer edge - outer middle - center - inner middle and inner edge.

lvresize
LVRESIZE(8) System Manager's Manual LVRESIZE(8)
NAME
lvresize - resize a logical volume
SYNOPSIS
lvresize [--alloc AllocationPolicy] [--noudevsync] [-i|--stripes Stripes [-I|--stripesize StripeSize]] {[-l|--extents [+|-]LogicalEx-
tentsNumber[%{VG|LV|PVS|FREE|ORIGIN}] | [-L|--size [+|-]LogicalVolumeSize[bBsSkKmMgGtTpPeE]} [-f|--force] [-n|--nofsck] [-r|--resizefs]
LogicalVolume{Name|Path} [PhysicalVolumePath[:PE[-PE]]...]
DESCRIPTION
lvresize allows you to resize a logical volume. Be careful when reducing a logical volume's size, because data in the reduced part is
lost!!! You should therefore ensure that any filesystem on the volume is shrunk first so that the extents that are to be removed are not
in use. Resizing snapshot logical volumes (see lvcreate(8) for information about creating snapshots) is supported as well. But to change
the number of copies in a mirrored logical volume use lvconvert(8).
OPTIONS
See lvm(8) for common options.
-f, --force
Force resize without prompting even when it may cause data loss.
-n, --nofsck
Do not perform fsck before resizing filesystem when filesystem requires it. You may need to use --force to proceed with this option.
-r, --resizefs
Resize underlying filesystem together with the logical volume using fsadm(8).
-l, --extents [+|-]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}]
Change or set the logical volume size in units of logical extents. With the + or - sign the value is added to or subtracted from
the actual size of the logical volume and without it, the value is taken as an absolute one. The number can also be expressed as a
percentage of the total space in the Volume Group with the suffix %VG, relative to the existing size of the Logical Volume with the
suffix %LV, as a percentage of the remaining free space of the PhysicalVolumes on the command line with the suffix %PVS, as a per-
centage of the remaining free space in the Volume Group with the suffix %FREE, or (for a snapshot) as a percentage of the total
space in the Origin Logical Volume with the suffix %ORIGIN. The resulting value is rounded downward for the substraction otherwise
it is rounded upward.
-L, --size [+|-]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
Change or set the logical volume size in units of megabytes. A size suffix of M for megabytes, G for gigabytes, T for terabytes, P
for petabytes or E for exabytes is optional. With the + or - sign the value is added or subtracted from the actual size of the log-
ical volume and rounded to the full extent size and without it, the value is taken as an absolute one.
-i, --stripes Stripes
Gives the number of stripes to use when extending a Logical Volume. Defaults to whatever the last segment of the Logical Volume
uses. Not applicable to LVs using the original metadata LVM format, which must use a single value throughout.
-I, --stripesize StripeSize
Gives the number of kilobytes for the granularity of the stripes. Defaults to whatever the last segment of the Logical Volume uses.
Not applicable to LVs using the original metadata LVM format, which must use a single value throughout.
StripeSize must be 2^n (n = 2 to 9).
--noudevsync
Disable udev synchronisation. The process will not wait for notification from udev. It will continue irrespective of any possible
udev processing in the background. You should only use this if udev is not running or has rules that ignore the devices LVM2 cre-
ates.
EXAMPLES
Extend a logical volume vg1/lv1 by 16MB using physical extents /dev/sda:0-1 and /dev/sdb:0-1 for allocation of extents:
lvresize -L+16M vg1/lv1 /dev/sda:0-1 /dev/sdb:0-1
