we changed the os hdd to .raw on zfs datastore, not zvol and wait if its getting better
any other experiences?

anothter test
write on qcow2, system freezes
write on raw via c$ share, 40mb/sec

Hi,
sound a little bit like io-issues with the underlaying IO system.

What kind of storage do you use (raid? (controller), disks/ssds? If zfs, how much ram the node hase free? cpu-power?

[cpzengel]

we have a 6x2TB 7,2K Constellation HDDs as Raid 10 with Cache and LOG SSD
We can reproduce those Freezes with qcow and zvol with writeback and writethrough on ZFS

Controller is an Intel in AHCI Mode

00:11.4 SATA controller: Intel Corporation C610/X99 series chipset sSATA Controller [AHCI mode] (rev 05)
00:1f.2 SATA controller: Intel Corporation C610/X99 series chipset 6-Port SATA Controller [AHCI mode] (rev 05)

CPU E5-2630 v3 with more than 52 GB free Space on Memory

Any Help apreciated!
