Shutdown VM
Adjust capacity in Unraid GUI VM page.
Download gparted, move iso to desired location, and set gparted iso as primary boot disk.
Boot into gparted iso and Extend vdisk to include new space.
Apply and shutdown.
Swap back to original vdisk as primary boot drive.
Boot up VM
SSH into VM (I use Moba)
List disks and storage:
df -h
List file system size
lsblk
Since this should be lvm, run lvextend:
lvextend -l +100%FREE <logical volume>
Mine specifically was:
lvextend -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv
Resize the file system so it can use all of that space.
resize2fs <file system path>
Mine was
resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv
"df -h" now shows correct size:
Message shows that disk has been resized successfully, which shows in "lsblk" again.
Once the LSI 9207-8i was updated from FWVersion(20.00.00.00) to 20.00.07.00 (latest at this time), the CRC and IO errors stopped. The remaining posts were to resolve possible data corruption issues on my drives.
Now SABnzbd is showing "OSError: [Errno 5] Input/output error: '/data/usenet_incomplete/...", and I opened a thread in the Binhex-SABnzbd channel here: https://forums.unraid.net/topic/44118-support-binhex-sabnzbd/?do=findComment&comment=1124052
