zpool

I had a mirrored zfs pool called "wd" with two disks: sda and sdb on a proxmox. To expand the disk, I detached sdb, added a new disk, sdc. Resilvered it and detached the remaining old disk sda. Unfortunately I messed up and now I would like to have my old two disks sda and sdb running again...

Hello! I had a problem with dirs which didn't mount on boot. This is fixed. Now, since a couple weeks I have mounting problems with 2 zpools: BLACK and TANK. At the moment I do it manually: zfs mount -a -Oafter every reboot... I am on the newest pve 6. Can anyone relate or give me advice how...

Hi, I want to use an HPE Microserver for Proxmox. It can take 5 drives. I want Proxmox and my VMs on a ZFS pool with redundancy. In my understanding I could create a rpool like the following and use mirror-0 for Proxmox and raidz1-0 for the VMs: rpool mirror-0 ssd1-256GB ssd2-256GB...

Hello I've built my zpool to use disk assignment (/dev/sda etc) I've now after setup and proxmox is live with lxc's and kvm on the disks, read and experienced that this is a bad move and that I should have used /dev/disk/by-id/ instead. Does anyone know how to convert an existing raid zpool...

I just recently upgraded the drives in my zfs pool, and while in the shell zpool shows correct amount of available space (about 11tb 4x4tb in raidz2). Promox is only showing just under 7tb worth of available space in the pool. Is there a way to refresh this or reset it? Because now my virtual...

Hey folks, I have a little R410 with Proxmox 5.3 and 4 4TB spinners in a ZFS striped mirror config. There is currently only 1 Server 2016 VM running, and it is basically only acting as a fileserver. I thought that the 4 spinners in a striped mirror configuration would perform much better than...

Hi there. I have a Proxmox installation that I installed on a ZFS zpool. The zpool was configured with the Proxmox installation and consists of two mirrored 500 GB SSDs, like this: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 mirror-0...

Hi everyone, I have 8 VDEVs on my proxmox server, I have had to resort to delay boot via /etc/default/zfs params in order for my system to boot properly. I'm looking to enable these: #ZPOOL_IMPORT_OPTS="-c /etc/zfs/zpool.cache" #ZPOOL_CACHE="" Has anyone here enabled these settings? If so...

Hello, we have a proxmox 5 and made an upgrade. the boot is on 2 disk raidz10 and we have other disk for ceph. the machine has rebooted and entered in "grub rescue". we load a live cd and execute the following commands: zpool list zpool list import -rpool That probably means that the...

Hello, we have to migrate a rpool on a raidz, to smaller disks and asking for the best way. At the moment we use 2 x Crucial M550 1TB (953.9GB) disks and want to switch to 2 x Samsung 960 1TB (894.3GB). The Samsungs are slightly smaller, so we can't just replace them. The next problem is, that...

4 months ago I installed PVE v4.4 on an eXT4 filesystem SSD. I put about 10 different containers on it and was the only user. I didn't use ceph or HA, and I had no other clusters--it was just one node with about 10 different LXCs. All containers were under 50% usage in their allotted storage...

Hi! I am relatively new to proxmox, but I need to post a question. running proxmox prior the upgrade to 5.1 I have a zpool running of 4 4TB disks. after the update, upgrade and dist-upgrade. I can no longer mount of dins the zpool at all. Al I get is a "could not activate storage 'rpool', zfs...

Hey guys! Did an update last night: apt-get update apt-get dist-upgrade after that, ZFS wanted a zpool upgrade -a which required a reboot. But after the reboot, i was stuck at busybox: i tried: zpool import -c /etc/zfs/zpool.cache -N rpool exit and it worked. Than i performed the zpool...

I am planning to use several virtual machines that will all use the same Dropbox account, and I want to use the deduplication abilities of ZFS to minimize wasted disk space. I also want the drobox data to be on a separate physical device from the OSs so that they do not take up read/write...

Instead of necroing a post from January of this year, I thought I'd ask a new one. In my configuration there are two hosts in a Proxmox cluster and two JBODs connected to each host. On each JBOD there is a local ZFS pool which I have configured in storage.cfg. What I'm seeing is that each host...
