Hi Friends,
We have multiple RBD images/devices.
We used fstrim to reclaim space on XFS filesystem on RBD images and it works
great.
Some of the RBD images, we share as block devices to Vmware using SCST. Any
suggestion on how to reclaim space on these devices?
The images are about 20TB
Hi Friends,
We have some inconsistent storage space usage reporting. We used only 46TB
with single copy but the space used on the pool is close to 128TB.
Any idea where's the extra space is utilized and how to reclaim it?
Ceph Version : 12.2.11 with XFS OSDs. We are planning to upgrade
Any help or direction in this below case is highly appreciated.
Thanks,
-Vikas
