Re: BUG: Incredibly high latency on HA luns in version 7509

It is incredibly annoying, yes. Also on top of if, the full-syncs after an unclean shutdown eat away our SSD write-endurance :oops: (all-ssd storage)

Re: BUG: Incredibly high latency on HA luns in version 7509

There's nothing mentioned in the release notes from yesterday.... :(
I'm still installing it for the LSFS fixes. Can't get worse that it currently is, can it?

Re: How to avoid a full resync after a node reboot?

Starwind support has advised us that this is a known issue and the workaround would be to disable L1 cache.
A fixed version is due "in a few weeks"

Thanks

Re: How to avoid a full resync after a node reboot?

Sure, here my specs: - 2 Images, 1 TB each - 2 Nodes, Sync - Currently, 4x 1 GBit - Network usage was zero pretty quickly after shutdown - I did not check which node was Master - 12.5 GB L1 Cache on each device Node 1 (the one who I tried to shut down) - 2x E5620 (2.4GHz, 8 Cores each) - 32 GB RAM -...

Re: System comes to a grinding halt on Sync

Yes, I had a situation where I accidentally took down the wrong node and needed to force a full re-sync with manual master selection. It still strikes me as very odd that nothing seems to be overloaded (network, disk, cpu, ram), but the connections to the hosts are still sluggish/slow. If that is th...

System comes to a grinding halt on Sync

Hi While re-syncing a HA cluster (we had some trouble with one node), all client-facing connections seem to come to a halt. VM's having 100% Disk usage and Disk Queue >10. Performance shows ~1000 IOPS / 27 MB/s. NIC's are currently 2x 1 GB, however, we are seeing a network bandwidth issue of about ~...

Release Notes / Release Notifications

I've seen the release notes for older versions in this forum, but I wasn't able to see the notes for V8.
Also, is there a way to subscribe to RSS/E-Mail Notifications when new versions get pushed out? I'm particularly interested in bugfixes of course.

Thanks
