RHEL7: lvresize on root volume hangs or does not complete, lvmetad blocked due to suspended LVM device
Issue
- LV resize hangs for root FS for RHEL7 hosts on vmware
- When I want to increase an LV, the command hangs and stays in the blocking state:
# lvresize -L +4G /dev/mapper/VolGroup00-LV_
Size of logical volume VolGroup00/LV_ changed from 24.00 GiB (768 extents) to 28.00 GiB (896 extents).
- On the console I see an XFS Hung Task.
- When does the behavior occur? Frequently? Repeatedly? At certain times?
- Frequently
- We have to reboot the vm to increase the filesystem, so its kind of urgent.
Environment
- Red Hat Enterprise Linux (RHEL) 7
- kernel-3.10.0-229.el7.x86_64
- lvm2-2.02.115-3.el7.x86_64
- lvresize of a root filesystem
