Re: Creating a Distributed logical volume
You can extend upto maximum of 21392MB since you have only 1337PE which gives 1337*16MB=>21392MB
#lvextend -L 21392 /dev/vgrblrel/lnprbl

Re: Creating a Distributed logical volume
Hi Ganesan,
Since the lv is distributed on both the disks I should have (13337*2)*2 size lv.

Re: Creating a Distributed logical volume
You are right. You can extend upto maximum of 21392MB*2 =>42784MB
I forgot to add the size of second disk.

Re: Creating a Distributed logical volume
Hi!
With lvcreat command i can only able to create lv of 32MB size for any other size it is giving error" Not enough PE's are available.
Created 32MB LV can be extended to single 32MB size further not even 64MB is allowed.
I am unable to understand why it is happening so, because there are enough free PE's are available on both physical volumes.
Logs are as follows
/ #lvcreate -D y -s g -L 40000 -n lnprbl /dev/vgrblrel
Logical volume "/dev/vgrblrel/lnprbl" has been successfully created with
character device "/dev/vgrblrel/rlnprbl".
lvcreate: Not enough free physical extents available.
Logical volume "/dev/vgrblrel/lnprbl" could not be extended.
Failure possibly caused by PVG-Strict or Distributed allocation policies.

Re: Creating a Distributed logical volume
Thanks all for your support, I have created distributed logical volume of size 40 GB.
I have created LV of 32 MB size then extended this LV with the help of a script with 32MB size increment step.

Sudhir
