Hi, I updated yesterday an two-node cluster from 5.4 to 6.0-5 (pve-no-subscription). They are only one VM on this cluster, which are running before the upgrade (live migrate to the updatred second node and later live migrate back). Due an configuration error, the second VM-nic was tagged in the...

Hi, I do yesterday an short performance test between pve5.4 + pve6.0 mainly to see, if the zfs performace are better, because we have some trouble with mysql-vms on zfs (ssd zfs raid1). Test: hardware: Dell R610 with 16GB Ram + HT on - 16 x Intel(R) Xeon(R) CPU X5560 @ 2.80GHz (2 Sockets) 2 *...

Hi, no - the disk should be scsi but the scsi controller virtio scsi... Udo

Hi, you can simply delete the vm-config if they doesn't exist anymore (but by sure to delete the right file!) rm /etc/pve/qemu-server/100.conf Udo

Hi, what do you mean with old?! What kind of server is it? I install pve on many old systems without any trouble (with the installer). If only the nic makes trouble, it's perhaps easier to install an intel-nic? But if the server are very old, you are perhaps not satisfied with the...

Hi Lucas, the trick is "can be something like"... mean, you have source lists, which uses oldstable stretch, wich must replaced by buster. to find your files use grep -r stretch /etc/apt/ sed is an streamline-editor and the command simply replace stretch with buster in the file (like vi...

Hi, with pve 6 the new corosync version is used. Are there any changes for the amount of cluster nodes in one cluster? If I remember right, for now is the limit 32 nodes, but less are recommendet (amount?). Udo

Hi, do you have any settings in the bios depends on clock source? How are the performance/powersave settings? Any difference with full performance mode? Udo

Hi, I've some R620 too but only two disks as zfs below an perc (raid-0 construct). All don't have any boot trouble... but an similiar effect i see at an R410 with enabled sata (bios). After disable sata in bios the boot went well without 10 minutes dead time. Udo

Hi, looks like trouble with an sata disk... This can happen with an damaged disk, or if you use an SAS-Disk on an Sata-Port! (See this some days ago). Udo

Hi, you don't wrote which perc do you have in the R610. With the BBU-Version you can't use pass through - for zfs you must work with single raid-0 which raided with zfs (ugly)! ZFS (zol) on SSD-Raid 1 is much slower than an raid-1 with the lsi-controller (don't mean the H330). Esp. with heavy...

Hi, is your downloaded iso broken? check the checksum. I have installed many times pve on Dell generation 11 servers, but allways from an usb-stick (copied iso with dd to the stick). Udo

Hi, Non-raid is the dell-naming for path through - so this is the right choice for zfs + ceph disks. About ahci - take a look here: https://www.diffen.com/difference/AHCI_vs_IDE Udo

Hi, you can try it, of course... but due the dependencies it's will be very hard (impossible I think) I guess. Udo

Hi, Proxmox-VE is debian based - so you can't run pve on other distros... Udo

Hi Wolfgang, in my case both servers use an seperate disk for swap... swapon NAME TYPE SIZE USED PRIO /dev/sdf1 partition 16G 147M -2 swapon NAME TYPE SIZE USED PRIO /dev/sdf1 partition 16G 0B -2 Udo

Hi, i have the same issue with the replication between two nodes. One VM was replicates from B to A every 15 minute and fails app. four times a day and one VM with the the same migration schedule from A to B fails not or only one times a day. I would guess it's the load (IO) and ZOL related in...

Hi, which versions you are running? Which process need the most ram? AFAIK there is/was an memory issue with ceph... get you the memory back if you restart the OSDs? (one by one)? Udo

Hi, which profile do you have selected in the bios? If isn't Performance you can have very weird IO-performance (had this with normal raid volumes on an R620). Udo

Hi, unfortunality the performance for zfs is not so good, like with lvm and an hw-raid-controller. We had some trouble with mysql-write-latencies on zfs (SSDs), which are gone, after switching to lvm-raid-storage (same SSDs). Pro for features, like replication for disaster recovery... Udo
