Why I cannot do this by UI? Is it intentional or the code for frontend was not developed?

After trying to restore zst backup I got: TASK ERROR: unable to restore CT 606 - command 'set -o pipefail && cstream -t 41943040 | lxc-usernsexec -m u:0:100000:65536 -m g:0:100000:65536 -- tar xpf - --zstd --totals --one-file-system -p --sparse --numeric-owner --acls --xattrs...

In cluster I've got two hosts. - vps1 - vps2 Each host got it local storage. - VPS1 got zfspool named zfs1-vps1 - VPS2 got zfspool named zfs1-vps2 On host VPS1 I click "Migrate" on some turned off VM/CT and click OK. There is always an error: Task viewer: CT 31337 - Migrate 2020-10-24...

I tried to create LXC Container using debian 10.0.1 template and ubuntu 19.04. Container created but after clicking it I see: I went on ssh console and did pct list: root@vps1:~# pct list can't open '/sys/fs/cgroup/blkio/lxc/200/ns/blkio.throttle.io_service_bytes' - No such file or directory...

That is the apache problem. Need to do more research.

Didn't work.

I did also some dirty thing after that .... I created that not-existent directories and files manualy using mkdir and touch. There are several bugs in proxmox or LXC ... with that but I cannot isolate that.

Container works but pct list get an error... can't open '/sys/fs/cgroup/memory/lxc/444/ns/memory.stat' - No such file or directory how to live?

This comes after restoring backup from proxmox 5.x with unprivileged=1. I did: zfs send | ssh zfs receive copy config from /etc/pve/lxc/444.conf to new serwer. pct start 444 Workaround works.

newest proxmox 6.x I tried to start lxc with GUI: Job for pve-container@444.service failed because the control process exited with error code. See "systemctl status pve-container@444.service" and "journalctl -xe" for details. TASK ERROR: command 'systemctl start pve-container@444' failed: exit...

From my point of view: - flashing generic LSI P20.0.7.0 version to H220 LSI gets about 30% !!!!!!!! - turned off NCQ (for i in a b c d e f; do echo 1 > /sys/block/sd$i/device/queue_depth; done) - we get about 3-6% - changed scheduler to none from mq-deadline (for i in a b c d e f; do echo none >...

@sa10 could You give me information about your test envirnoment? For real good compare I need ZFS dataset parameters: - recordsize, - ashift, - compression, - atime.

I did some tests for others with different recordsizes. recordsize 32K, pool1 write bs=1mb iodepth 4 write: IOPS=499, BW=500MiB/s (524MB/s)(10.0GiB/20485msec); 0 zone resets clat (usec): min=8, max=12788, avg=6004.62, stdev=2669.45 read bs=1mb iodepth 4 read: IOPS=2323, BW=2324MiB/s...

Next test I did is different ashift: ASHIFT = 0 write bs=1mb iodepth 4 write: IOPS=509, BW=510MiB/s (535MB/s)(10.0GiB/20087msec); 0 zone resets clat (usec): min=8, max=107857, avg=5888.93, stdev=2487.83 read bs=1mb iodepth 4 read: IOPS=2244, BW=2244MiB/s (2353MB/s)(10.0GiB/4563msec)...
