Hello guys. After struggling with this problem fro a year in OVH datacenter i finally might have something ! Standard options in sysctl are: vm.dirty_background_ratio = 10 vm.dirty_ratio = 20 And when my SERVER HAVE 265GB or DDR memory !!! - then : 256 GB * 20% = 50 GB So in that case if i am...

Its a mess and i had problem. I will try with those here, thx for tip. I will respond if i succeeded. EDIT: Yep, this solved all my problems :)

Hi guys. The howto form proxmox wiki disappeared and i cant het drbd9 working on my 2 node cluster + 3 as witness. So far i made: vgcreate drbdpool /dev/sdb1 i added drbdpool in proxmox gui and selected as shared. Now when i am creating new VM or LXC, i dont see image cloned to the second...

/etc/pve/nodes Search in all nodes like /etc/pve/node1/qemu-server /etc/pve/node2/qemu-server for this VM config it should be somewere :) This is Proxmox cluster or one server ? Search for this config somewere :) your MV id is 102 right ?

P.S - i am using Proxmox 4.2 and i adive you to use it also :) Another approach: You can remove disk record from VM config open thix VM config: nano /etc/pve/qemu-server/102.conf delete line cointaining this disk something like ide0:.... , save and again try to delete whole VM :) also check...

Try to create this LV manually and then delete in gui ?

So it might be an Array. ok then.

Sure. HP ProLiant DL380 G7 Smart Array P410i ( 05:00.0 RAID bus controller: Hewlett-Packard Company Smart Array G6 controllers (rev 01)) 2x 250GB ssd Crucial MX200 in Raid1 Created 2 virtual disks /dev/sda for proxmox and /dev/sdb for drbd Other servers (but all others are Dell) but with...

Yeah but this is /dev/sdb1 LVM with no filesystem so it doesnt mount anything right ? Still high IO.

its not the case. i have like 10x better performance on other nodes in 3.2 pve also on mx200 crucial (those disks are enterprise level :)

More screenshots. Anybodo know why is this happening ? As i see, 10MB/s makes ssd used at 100%. Why ? On node2 there is MOVE DISK from NAS to internal DRBD on ssd. Node4 wchich is connected with node2 with DRBD

IO delay is still unsolved. But i solved drbd sync speed :) https://forum.proxmox.com/threads/settings-drbd-doesnt-presist-after-reboot-global_common-conf.27955/

THX !!!! I finally solved it :) Scenario: Fresh booted nodes. I am creating new disk via GUI. Syncing starts and presist at about 20-30mbits/s Then i just simply execute this command to only one node (it will automaticly send to other nodes too) you can monitor if changes apply by: watch 'cat...

thx for info. So i sould set in rc.local proper drbdmanage command then

Hi, I have one cluster with really low fsync rate and i have some problems with high IO while converting qcow to raw on it. And also with different operations. Specs: Block size is 4K , Ext4, problem is also on LVM 05:00.0 RAID bus controller: Hewlett-Packard Company Smart Array G6 controllers...
