Share storage using 9p https://forum.proxmox.com/threads/virtfs-virtio-9p-plans-to-incorporate.35315/#post-184993

I dont use NFS but I found old line in /etc/exports /media/zfs_pool/cloud/mk 10.10.10.16(rw,sync,no_subtree_check)

Set sharenfs off on ZFS and add it to the /etc/exports

Edit /etc/exports file and reload NFS service #exportfs -a

If you want to configure SAMBA use google. IF your two LXC containers are in the same server you can try folder share https://pve.proxmox.com/wiki/Linux_Container#_bind_mount_points

I guess ZFS NFS and SAMBA export is broken. Try to edit manually and export.

Looking to your ZFS status I can suggest you to make a scrub after resilvering will be done.

Resilvering- the process then one or more disk have missing new data. ZFS check and sync pool data to make 'delayed' disk to catch up timestamp

I`m very old Proxmox user. I can`t afford to buy a subscription but then I want to get stable version I always look at https://pve.proxmox.com/wiki/Downloads '# pveversion -v' section to know stable packages numbers before I do update.

ZFS is local file system. Not network. It is not ceph or gluster.

Not so long time ago I and my cousin had some problem with his ZFS pool. Pool is 8 disk raidz2 configuration. At the beginning one HDD started to show checksum, r/w error on ZFS pool status. Scrub show no error but disk error count still occurs. Suddenly another HDD showed smart errors and we...

It may be relate to hardware. Check the cables and so on.

Everything looks normal. Not sure about compression. I manually set to lz4. ZFS pool speed depends on slowest disk performance. To speed it request bigger ARC. Then ARC is cold you get disks very busy. To make ARC 'hot' some say it takes 2 days to warmup. ZFS advantages have it own cost.

You are very distracted. Can you replay to post above ?

for i in /dev/sd{a,b}; do smartctl -i $i | grep Sector; done # zpool get ashift zfs get volblocksize,compression As you can see only 37% data comes from ARC cache. My server with 12G ARC hit rate is 87%. You can try to disable prefetch #echo 1 >...

To make ZFS work better with the same resources is tricky. 1. What is your disks sector size? 2. What is your ZFS pool ashift setup? 3. What is your ZFS volume volblocksize, compression? 4. ARC size? #arc_summary

ZFS have a tool like "#zpool iostat -v 1" to see disk activity. ZFS speed depend on slowest disk on the pool. If you see big activity different between disks - it may be: 1. You are using different model of disks. 2. If your ZFS pool is made from identically disk -> one of the disk have problem...

It is normal. My ZFS pool with 2 hdd mirror or another pool with 3 hdd raidz VM startup takes some time. But in ZFS pool with 3 SSD raidz VM boots instantly.

Build ZFS pool from 8 or more disk if you want fast VM startup, or use SSD only.

You have pool from 2 disks. Don`t expect fast read, except your pool are from SSD.
