Volume not expanded after adding higher capacity disks
Hi, I have a ReadyNAS NV, and I've been running X RAID with 4 x 1 TB Disks. Recently, I've been replacing the disks 1 by 1 with 2 TB disks. After last night, I finally now have 4 x 2 TB Disks i...
If the volume looks synced, try rebooting it.
What firmware are you running?
Reboot seemed to have done something. I now see in the Volume page of Frontview showing me the right amount of disk space (~2TB) are allocated on each disk, but the overall capacity of the NAS hasn't changed. It is still stuck at 3TB, not 6 TB as I was expecting.
I then saw this error in the log: "Disk capacity expansion error. resize2fs". After googling this for a while, this seems to be a known problem with upgrading to 2 TB drives in ReadyNAS: https://community.netgear.com/t5/Using-your-ReadyNAS/Disk-capacity-expansion-error-resize2fs-Readynas-NV-F/td-p/653186
Am I now stuck with no option but to initialize my ReadyNAS from scratch? What a painful process trying to move from 4x1 TB to 4x2 TB. Had I known this, I would have reconsidered. I now have spent over $300 on new disk drives, and still not getting the capacity that I wanted. I've always been a ReadyNAD fan, but this is got to be the biggest disappointment with this this product.
Let's first confirm that this is the issue -
Please download the logs from FrontView > Status > Logs > Download All Logs.
Look at system.log and search for "block size". Is it set to 4096?
Though I get the disappointment, the block size issue was a time bomb in the original 3.x NAS firmware (years before 2 TB drives were on the market).
In volume.log, I see this line:
Block size: 4096
and in system.log, I see this line:
system.log:Aug 30 16:58:53 readynas kernel: RAMDISK driver initialized: 16 RAM disks of 16384K size 1024 blocksize
and I'm running firmware RAIDiator 4.1.14 [1.00a043]
So, what's my option now? Thanks very much for looking into this.
