Can't expand volume after adding drive to RAID 5 storage pool

Post by zathrath03 »

I added a fourth HDD to my RAID 5. The storage pool correctly increased for the added drive. However, when I attempted to expand the volume, the volume capacity is grayed out.

Any ideas on how to fix this?

SOLVED:

Turns out you need to disable the SSD cache to be able to adjust the volume size. Not sure why, but it worked, so I guess the why doesn't really matter.

Thanks for posting the resolution, just in case it ever happens to me.

Saying that, I have 3 drives in RAID5, and then 2 in RAID1 for "safety".
