Hi All, I extended the Linear LVM without Unmounting the Logical Volume. But Most of the docs suggest to unmount the LVM in shrink process.
I believe not MOST but EVERY docs suggest this ;)
1. Is it possible to shrink the LVM at Runtime (with out Unmount). If yes, What is correct way to do it.
You can shrink any lvm2 device online - as long as you don't care about data on this volume - but somehow I don't think it's matching your case...
In typical case you want to shrink filesystem first. lvreduce support option '-r' but for obvious reasons requires umount....
Also I found in some places that only few file system supports Runtime Extend and Shrink of LVM. 2. What are file systems supports LVM extend and shrink without Unmount
Well - btrfs is known to be capable of online shrink - but in that case you don't need lvm2 ;)
None of the filesystems like 'extX', 'xfs', 'reiserfs' could be reduced online. Zdenek _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
