Write speed to OMV dropping to 10MB/s

cross25 · 30. Mai 2016

Hi,

I'm on HP Microserver :
Proc : Xeon E3 1230
RAM : 16 GO
Vitualization : ESX V6 Update 2

VM OMV full update on SSD
Share SMB/CIFS

I got a strange problem with my OMV :
- when i copy data on it a got a slow write about 10mo/s.
- If i copy data on network a got no problem but on Windows VM to OMV i got a slow write.
- If i copy data to OMV to Windows VM i got 100MB/s
- If i use the network for copy data with a computer to OMV i got 100MB/S

I try to make another VM, but i got the same issue...

If someone got an idea ?

thanks by advance.

This is a known issue not related to OpenMediavault but an issue of VMWARE (I had the same issue)

issue is within the scsi-hpvsa driver. everything above the .88 is causing this.
force to a downgrade of the driver:

esxcli software vib remove -n Hewlett-Packard:scsi-hpvsa
esxcli software vib install --viburl=/vmfs/volumes/DATASTORE/scsi-hpvsa-5.5.0-88OEM.550.0.0.1331820.x86_64.vib
