ESXi 5.5 only 4TB usable for datastore

D3fc0n — Tue, 05 Apr 2016 06:58:29 GMT

Hello all

Although in vSphere Client a capacity of 5.46 TB is visible, I can only use 3.64 TB for a datastore.

Configuration:

- HP Proliant Microserver N40L

- HP Smart Array Controller P410/512 BBWC, FW 3.66

- 4 x 2TB as one Raid5

- HP-ESXi-5.5.0-iso-5.72A

I read a lot of articles about >2TB limitations of older ESXi versions or controllers, 4TB limitation of C# vSphere Client, old firmware and esxi driver problems, etc.

But I could not figure out the problem.

The P410 controller shows 5.5TB:

~ # esxcli hpssacli cmd -q "controller slot=1 show config"

Smart Array P410 in Slot 1 (sn: PACCRID110510NR)

array A (SATA, Unused Space: 0 MB)

logicaldrive 1 (5.5 TB, RAID 5, OK)

physicaldrive 2I:0:5 (port 2I:box 0:bay 5, SATA, 2 TB, OK)

physicaldrive 2I:0:6 (port 2I:box 0:bay 6, SATA, 2 TB, OK)

physicaldrive 2I:0:7 (port 2I:box 0:bay 7, SATA, 2 TB, OK)

physicaldrive 2I:0:8 (port 2I:box 0:bay 8, SATA, 2 TB, OK)

SEP (Vendor ID PMCSIERA, Model SRC 8x6G) 250 (WWID: 5001438013D9F37F)

ESXi obviously recognises the same size:

~ # esxcli storage core device list

naa.600508b1001ca5e68adc0bc4bc508d6e

Display Name: HP Serial Attached SCSI Disk (naa.600508b1001ca5e68adc0bc4bc508d6e)

(etc...)

But only offers 4TB:

~ # df -h

Filesystem Size Used Available Use% Mounted on

VMFS-5 3.6T 2.1T 1.5T 58% /vmfs/volumes/mainstorage

vfat 249.7M 177.2M 72.6M 71% /vmfs/volumes/aeda2aeb-c934ad60-46ce-cb77abdfabaa

vfat 249.7M 175.9M 73.9M 70% /vmfs/volumes/c8ace7e9-a96a5914-16d4-a697ad4634d9

vfat 285.8M 191.4M 94.4M 67% /vmfs/volumes/55d7af6e-a25f7c97-c3ec-6805ca0de93c

I tried to increase the datastore size, last used sector was 11720890367 and last offered sector was 11720890510 which does not really seem to result in an increase of 1.8TB.

Thanks for your help.

Can you please share the output of "esxcli storage filesystem list"

Looks like vmfs is able to see only 4TB of space on that disk. Can you post the output of "partedUtil getptbl /vmfs/devices/disks/naa.600508b1001ca5e68adc0bc4bc508d6e"

Ok:

From your output it shows that there are two vmfs partitions

3 10229760 3907029134 AA31E02A400F11DB9590000C2911D1B8 vmfs 0

4 3907031040 11720890367 AA31E02A400F11DB9590000C2911D1B8 vmfs 0

One partition with 1.8Tb and another one with 3.8 TB. This is the reason you are seeing only 3.8 TB

I dont know why the 1.8TB vmfs volume is not listing anywhere ( that is not listed in esxcli storage filesystem list also). Have you manually created any partition before. In case if you think there is no data in that 1.8 TB vmfs partition you can delete it using partedutil command and then use that free space to extend the existing 3.8TB. But be sure before deleting the partitiaon

YES!

I deleted partition 3 and then could increase the datastore with the missing 1.8TB using vSphere Client 5.5.0-3024345.

This is the result:

/vmfs/volumes # df -h

Filesystem Size Used Available Use% Mounted on

VMFS-5 5.5T 2.1T 3.4T 38% /vmfs/volumes/mainstorage

vfat 249.7M 185.2M 64.5M 74% /vmfs/volumes/aeda2aeb-c934ad60-46ce-cb77abdfabaa

vfat 249.7M 182.4M 67.4M 73% /vmfs/volumes/c8ace7e9-a96a5914-16d4-a697ad4634d9

vfat 285.8M 201.6M 84.2M 71% /vmfs/volumes/55d7af6e-a25f7c97-c3ec-6805ca0de93c

I cannot explain how the partition got lost, but I read about vSphere C# Client having an issue with partitions >4TB.

Obviously this is solved with the current version. I upgraded to 5.5-U3 in the meantime.

Thank you very much!
