Logical Volumes not using the total disk capacity

Postby dscarlat » Fri May 19, 2017 11:06 pm

Hi all, I've a TS-439Pro with disks from segate model st3000vx000. In "Volume management" the disks appear in the Physical Disk list and report the right capacity 2792.53GB (3TB). When I create the volumes (I've tried single disks, RAID, Linear disk module...) the final size is only 2Tb for each disk.
These disks was previously used in a QNAP TS-219pII and the volumes had the correct 3TB size...
Any idea on how to make the NAS recognise the full size of the disk?
Thanks!

Hi and welcome to the forum. :)

When asking a question, please include your NAS firmware version and build number.

Can you please post a screenshot that shows the reported size as 2TB?

I've switched to pure Debian on my production NAS (TS-569 Pro), with the backup NAS (TS-559 Pro+) to follow, so I'll no longer be able to use or support QNAP's firmware. This means no more closed-source software, "Malware Removers", etc ... If you have the means, I highly recommend it. Powerup/poweroff times are < 1 minute. :D

Thanks a lot!

Model:TS-439 , Current firmware version:4.2.6, Date:2017/05/17

Here you have the screenshot. Drive 3 capacity is 2794.52 but Single Disk Volume on Disk 3 has 2014.39 Gb Size.

Any idea?

In case it helps, for disk 3 I see this partitions:

[/] # fdisk -l /dev/sdc
You must set cylinders.
You can do this from the extra functions menu.

Disk /dev/sdc: 0 MB, 0 bytes
255 heads, 63 sectors/track, 0 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sdc1 * 1 66 530113+ 83 Linux
/dev/sdc2 67 132 530145 82 Linux swap / Solaris
/dev/sdc3 133 267286 2145914505 83 Linux
Partition 3 has different physical/logical endings:
phys=(1023, 254, 63) logical=(267285, 254, 63)
/dev/sdc4 267287 267348 498015 83 Linux
Partition 4 has different physical/logical beginnings (non-Linux?):
phys=(1023, 254, 63) logical=(267286, 0, 1)
Partition 4 has different physical/logical endings:
phys=(1023, 254, 63) logical=(267347, 254, 63)

I formatted the disks in a linux box following QNAP support advice and now the full capacity is recognized.

You could have wiped the partition in the NAS and then pulled it out, waited, then re-inserted it. The NAS would have seen it as a new drive.
