clear tasks from WebUI
by David David
Hi
oVirt 4.2.5.2-1.el7
I tried to delete an Illegal vm disk and that failed. Then I completely remove
the VM who had that broken disk. But task is stuck in the WebUI from my
previous disk deletion attempt
vdsm-client Host getAllTasksInfo on the SPM host, shows no tasks.
How do I clear the tasks from the WebUI?

high load on hosts
by Jayme
I'm wondering how I can best limit the ability of VMs to overrun the load
on hosts. I have a fairly stock 4.2 HCI setup with three well spec'ed
servers, 10Gbe/SSDs, plenty of ram and CPU with only a hand full of light
use VMs. I notice when the occasional demanding job is run on a VM I'm
seeing load average on host node shoot up in to the 20-30s, how can a
single "medium" vm cause host load to rise so high?

Choosing optimal vdo Write policy on LSI Raid device that always report write-trough to the OS
by guillaume.pavese@interact-iv.com
Hi,
I am evaluating vdo for an hyperconverged ovirt cluster.
The volume is on RAID device supported by a LSI (Dell Perc H710) controller with Write Back cache enabled :
Current Cache Policy: WriteBack, ReadAdaptive, Cached, Write Cache OK
However these LSI controllers (all PERC series on Dell servers), as per documentation, always report cache policy as writethrough to the OS, no matter if write back is effectively enabled or not :
cat /sys/block/sdb/device/scsi_disk/0\:2\:1\:0/…
[View More]cache_type
write through
vdo by default choose its write policy (sync or async) accoring to the cache mode reported by the disk. So with cache policy auto, in that case it is set to "sync" :
write policy: sync
So my question :
In this configuration, write cache enabled on the raid controller but reported as write trhough to the os, should I manually set vdo cache policy to async for optimal performance?
Thanks for your help
