I think its lvm-thin, I'm not 100% sure how I even set it up, I think I just followed the defaults in the guide. My storage config looks like this. dir: local path /var/lib/vz content iso,backup,vztmpl lvmthin: local-lvm thinpool data vgname pve content...

Hey Everyone So I have a server with a raid controller with 8Gb cache onboard and some nearline SAS 7200 (yes i know they are not the best drives) in raid 5. Server is an ibm SR550 The max disk performance sustained is about 150mb/s read and write. My problem is that when I restore a 300Gb...

Ok.. more updates haha, So there is already a thread : https://forum.proxmox.com/threads/blue-screen-with-5-1.37664/page-10 And seems latest kernel 4.13.8-26 fixes this? What is weird is that I have 4 server 2016 VM's(only 1 is production sofar the others are test) and the first one runs...

I have some more info, it turns out that windows is crashing with: The bugcheck was: 0x00000109 (0xa39fdadeac097720, 0xb3b6e764fe8a8a51, 0x0000034000000000, 0x0000000000000017) I googled that and found: This problem occurs because the system detects a Critical MSR modification, and then it...

I just did a brand new clean windows server 2016 vm (cloned from a template) It runs great but then the next day the console just shows "Start boot option" bios screen and the vm is no longer working but still shows running status. I cannot stop/reset/shutdown it, just get errors after a very...

Well even after I rebuilt everything on just the SAS drives the result was the same. The problem in the end was my own stupidity... I had forgotten that somone else deleted my array and recreated it when we got the server and they did not enable the controller cache settings again. Once I turned...

There is an update but IBM is such a bunch of ***** they only have packages for red hat and windows. And for sme reason the updater that should work through the xclarity bios thing isnt accepting the file either:( I'll have to struggle with that today.

So I just rebuilt my LVM to just my SAS drives but I still ahve two enterprise grade 32Gb SSD's in the server and I saw a guide online saying LVM supports cache like so : Create The fast method is creating a PV (if necessary) on the fast disk and add it to the existing volume group: # vgextend...

Soo been reading a bunch of stuff on the forum and went to double check the settings on the HW raid controller.. apparently all the cache settings was turned off! Enabled cache and now it's doing much better.

Thing is my FS is RAW,because the disks are managed by an LSI raid controller. The actual throughput on the drives doesn't seem to be the issue, with DD I'm getting good enough speeds that the disks would outperform the LAN by miles. Whats happening though by the looks of things is when using...

I completely wiped out my system and started from nothing after I assumed I made a mistake. I thought because I mixed SSD and SAS drives in LVM it caused my IO issues. This time I completely left the SSD drives untouched and installed proxmox on the large SAS raid 5 array on the hw controller...

Hey Udo Thanks a bunch for the info, I don't really have any spare drives at the moment, only usb ones. I'm just going to backup the entire VM to a NAS and then wipe out all and start over using your instructions. So what I want in the end is to create a new VG with the SAS drives only like...

Ok so I have more info that might help. hdd tune read test: The IO delay is < 1% on reading and the server is still extremely responsive with no problems, the read rate is ~200mb/s In windows disk response time was <50ms the entire test. So reading = no issue. Next up I used crystaldisk bench...

My problem at the moment is I can't even get the windows VM to boot up when I enable the passthrough, it gets stuck trying to figure out the hardware and just never starts up. There is no updated driver for windows 10 /server 2016 since usb3 is supposed to be native to those OS's. The link...

The SSD's are IBM PCI-E riser cards enterprise grade. This server has been running all of 1 week I can't imagine that write endurace would be the issue here. Not sure how LVM fills the drives but the SSD's make up 7Gb of 20 TB and I already put over 1Tb of data on the two combined VM's. Sure the...

Initially after the restart it looked better but after a few minutes it became so slow that clicking on things in RDP took more than a minute before anything happened and then soon after that it completely stopped responding to any new commands. The IO Meter on the host showed max spike of 10%...

You're right sorry I should have given more detail. This is a fresh install of PVE 5.1 on an IBM SR550 server. specs: CPU(s) 32 x Intel(R) Xeon(R) Silver 4110 CPU @ 2.10GHz (2 Sockets) Kernel Version Linux 4.13.4-1-pve #1 SMP PVE 4.13.4-25 (Fri, 13 Oct 2017 08:59:53 +0200) PVE Manager Version...

I'm running a windows server 2016 VM on proxmox, so far it has no roles defined or anything just core + gui installed. I have one shared folder and I'm busy copying data from our current file shares onto it using Allwaysync software over the network. While this copy process is happening the...

I notice with the 5.1 update the forum is really busy dealing with issues but does anyone have some ideas of things I can try please? Or maybe aiddtional commands etc to give more information.

Quick update that might help. I have a win7 VM install as a test also so i mapped the same port to it (removed it from the win 2016 VM) downloaded a generic usb3 driver from lenovo (its a lenovo server) for windows 7 and it worked! The drive shows up, I can see the files etc and my dmesg log...
