we made a LUN extend on a VNX5300 (original lun size 300 GB) creating a metaLUN (actual metaLUN size 600 GB) for a Linux Red Hat 6.4 host.
The LUN extension has gone well, but now we are going really crazy to reconfigure LVM.
We can see the partition increased from 'fdisk -l' command output, but even after we tried to increase PV size with command 'pvresize', we still see 0 free PE inside the 'pvdisplay' command output.
Then we can't perform 'lvextend' and 'resize2fs' to increase our volume/filesystem.
Anyone could help us?
Many thanks in advance.
have you tried that with file system unmounted ? If you are using LVM why not create a brand new LUN, extend vg/lv/fs ? You get more queues in the OS = better performance.
