Hello all. Is it possible to let a VM tell Proxmox "from now on, boot from network instead of from scsi0"? For servers with IPMI it can be done via ipmitool, but for VMs? Tks, Diego

Hello all. I'm going to configure a new PBS server. It currrently hosts 8 x 16TB disks, but "soon" (during the year, not next week) we'll need to add another 16 x 16TB (for a total of 24 x 16TB). I thought to use RAIDZ3, starting with the current 8 disks and expanding later with the new ones...

Hello. It's about a week I'm banging my head on this. I had a 9-nodes cluster (virtN, N=1..9, 192.168.1.3N/24). I now have to replace all the nodes with "new" hardware, so I started from the nodes 4..6. As described in the docs: - shutdown virtX and start install on new HW, so no risk old virtX...

Hello all. I'm facing a strange problem. I have a cluster of 9 Proxmox 7.1-12 servers on identical HW (old Asus servers). Yesterday I rebooted the last 3 nodes I added recently and only one returned online. The other two rebooted, but failed to bring up networking. If I connect "locally" (IPMI...

Hello all. At the end of 2021 I upgraded all the six existing nodes to 7.1 (migrating VMs back and forth w/ no issues, except higher load). While at it, I also installed 3 new nodes and added 'em to the cluster. The cluster now sees the 9 nodes online and OK. But when I try to live migrate a VM...

Hello. After last upgrade, I sometimes get migration errors. I'm using a shared storage (Dell MD3200) system. This one seems a race condition: 2019-04-16 12:29:34 migration status: completed can't deactivate LV '/dev/DataBox1_r6/vm-116-disk-0': Logical volume DataBox1_r6/vm-116-disk-0 is used...

Hello all. I'm having troubles with access to Dell MD3800i (iSCSI w/ multipath). The nodes configured to use it gets marked with a grey question mark after some (random) time. Sometimes the running machines keep working, sometimes not. I got the feeling that it's something workload-related: the...

Hello all. Seems the procedure is still mostly manual and the same since Proxmox 1 (ive years and two major releases): http://forum.proxmox.com/threads/3578-Removal-of-iSCSI-disk-causes-system-to-hang (last message contains the details). Currently, after you've removed both the LVM and its...

Hello all. I just added an MD3800i (ISCSI) to my cluster. I configured it to not require authentication, to rule out possible problems. The first node sees it and can access the LUN, but the other two nodes seems to be unable to see the LUN. Is there something I could be missing? MD38xx admin...

Hello all. I just installed a new machine that shoul be joined to my cluster, but when rebooting I get: cannot import rpool: one or more devices are already in use And an hint to use zpool import (I tried, but it fails w/ the same error). I have no experience on ZFS so I don't really know how...

Hi all. I'd like to maximize throughput while having link redundancy. My servers have 4 NICs, so I thought to bond all of 'em and send a couple on one switch and the other couple to another switch. But some questions arise. 1) should I create one bond (of 4 interfaces) or 3 bonds (bond0 for...

Hi all. I currently have a two-node cluster using a Dell MD3200 as LVM shared storage (two LUNs, one for OS and one for data LVs). For disaster recovery, I'd need to automatically send a backup of some VMs to another Proxmox cluster, that uses iSCSI-backed LVM. But till now I couldn't find a...

Hello all. I just noticed that "disk IO" graph copies "network traffic" one. Just to say, when I run bonnie++ in the vm, nothing changes. If I get a big file via FTP, I see that both network-in and diskread go up... Probably a typo (or copy&paste error) somewhere... Luckily nothing critical :)...
