I don't know what are you insinuating, or what others understood; I have not blamed anyone. A staff member said "I`m probably not doing it right", insinuating I am dumb or something. * Yes * Yes * No, this is not mentioned clearly * Here: 1 drwxr-xr-x 2 root root 5 Mar 14 09:50 . 9...

Well, this is the only "ready to use" ISO the hosting provider offers; 6.1 not added yet. Still, https://www.proxmox.com/en/news/press-releases/proxmox-ve-5-4 says last year so it's not that old ?

I`m not sure I understand any of this ? Here you go: ------------------------------------------------------------------------ ZFS Subsystem Report Sat Mar 14 20:34:10 2020 ARC Summary: (HEALTHY) Memory Throttle Count: 0 ARC Misc...

How can I do it wrong when it's after your docs ? # ZFS tuning for a proxmox machine that reserves 64GB for ZFS # # Don't let ZFS use less than 4GB and more than 64GB options zfs zfs_arc_min=4294967296 options zfs zfs_arc_max=68719476736 # # disabling prefetch is no longer required options zfs...

I just created /etc/modprobe.d/zfs.conf , set a limit of 64 GB, rebooted, and the limit is still the same - 50% of whole memory. So the conclusion is, creating this file makes no sense ?

Thanks

Does that really work ? It does not make any sense lol.

Hello, I installed 5.4 from iso, and I cannot find /etc/modprobe.d/zfs.conf to be able to limit the ARC. Am I missing something ? Thanks

I was having over 50% being used of 256 gb ram, while I was testing. The system hang even with so much ram used, the moment you tried to move a big file. After disabling l2arc, the performance was .. 100 iops compared to what I posted, after enabling it back the performance dramatically...

Yep, randomly gets stuck again. IO goes up to 60% and nothing can be done anymore. Not even reboot...

Point of interest, I have re-set as follows: # ZFS Intent Log, or ZIL, to buffer WRITE operations. # ARC and L2ARC which are meant for READ operations. # ARC # 5 gb min - 10 gb max options zfs zfs_arc_min=5368709120 options zfs zfs_arc_max=10737418240 # metadata limit # 5 gb options zfs...

I cannot get my head around this, as I`m experiencing some very weird server IO delay and server crash. It seems I have this exact same issue [1][2]. The setup has ZFS + ZIL + L2ARC, however the RAM was getting used up to 100+ GB and the L2ARC was (and is set) to 150GB/read/write on the SSD...

I haveAMD Epyc 7371 .

numactl -H

You are correct, meanwhile I was searching about this. What can I say, long live AMD ?

Hello, I`m very confused with NUMA, as I read from docs you have a NUMA capable host if you have multiple CPUs (sockets). However I have installed Proxmox 6.1 (latest) on a AMD EPYC 16 core CPU, and the command to check available numa returns: available: 4 nodes (0-3) node 0 cpus: 0 1 2 3 16...

Thank you, however this server cannot be customized... it's "AS IS"...

Hello, I am having a hard time figuring out the best average values to limit read/write/ops for a "normal" HDD like HGST_HUS726020ALA610. I got 2x2 TB of these in SoftRaid, and machines running only Windows server. Because these machines have SQL on them sometimes a machine can read/write so...

Several articles regarding this issue already, including me experiencing it.

Bump ?
