Hi, we just got hit by a bug with 4.15.18-10-pve Kernel and i40 10G network cards from intel. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1779756 Problem seems to be fixed in kernel version >=4.18. Will 4.18 be available in proxmox in the near distance? Any help is greatly...

SOLVED. One of the SSD drives had very poor performance and just got replaced by samsung RMA.

I now got your point that you do not like this SSD drives and would not use it. No smart IDs that would indicate an issue with the drives at all. I do not have windows available to test the controller. I will get the same controller (but with vendor brand from fujitsu) and will check if...

Maybe you missed this in my text: "ssds have no smart errors. did short and long tests.". And you may have missed this as well "Removing ssd drives from raid controller for test and attach to onboard sata-port. write rate is ~ 400MB/s." So the drives are ok and can be fast.

750 Evo Samsung SSD. Performance is almost the same with fio: root@proxmox:/ssd# fio --max-jobs=1 --numjobs=1 --readwrite=write --blocksize=4M --size=5G --direct=1 --name=fiojob fiojob: (g=0): rw=write, bs=4M-4M/4M-4M/4M-4M, ioengine=psync, iodepth=1 fio-2.16 Starting 1 process fiojob: Laying...

Hi folks, I'm looking for ideas to gain performance on my ssd raid on a lsi 9260-8i controller. proxmox 5.1. FS is ext4. I have 2 x Samsung ssd as raid1 and 2 x WD SATA HDDs on same controller. /dev/sdc1 457G 38G 419G 9% /sata /dev/sdb1 208G 3.1G 205G 2%...

Hi Folks, is there a way to set bwlimit per storage? I woud like to specify say 600KB for a uniq storage but keep fullspeed on any other storage. Any help is greatly appreciated. Thanks.

Hi Leute, wie kann ich storageabhängig das bwlimit setzen und dennoch über die GUI automatische Backups fahren? Ich hätte gerne eine Option bwlimit pro konfiguriertem Backup in der GUI oder eine Option in der vzdump.conf, mit welcher ich bwlimit auf ein spezielles Storage anwende. Ideen? Danke!

Seems that this is only during i take backups with snapshots. Is this a known issue, that during a snapshot, the system is rather slow?

Dear Users, One VM (Server 2012 R2) out of 5 randomly hangs and logs EVENT-ID 129 - viostor. Latest stable virtio-drivers are installed and active. All Disk related Tests on physical HW are fine. Fujitsu Server with SSD-Drives on Raid-Controller with BBU. So disk i/o is not the issue i think...

Not yet as its quite an act to move a complete VM to a different storage. Cache is not set. This is recommended in the proxmox wiki. Should i change it?

Anyone?
