  1. Coalesce disks

    Ciao, this is the situation: multiple VMs migrated from XenServer to PVE, each one with their original disks (i've done an automated migration script that will move virtual disks from XS to PVE). Almost all of these server has multiple disks connected with A LOT of wasted space. In example...
  2. Debian boot hangs

    Hi. after a proxmox hard crash (still I don't know why) , all VMs are up and running properly except one (debian, like all others). Boot process is stuck at this: i've reboot the VM with a debian rescue disk, mounted everything, run fsck on everything and no errors were found. Also, from the...
  3. [OT] Export disk lists from XenServer via API

    Sorry for the OT but I don't know where to ask. I have to move a bounch of VMs from XenServer to Proxmox, to do so automatically with a script made by me, I need to know the exact disks lists and sizes attached to the XS server, via http call. Reading the OVA.xml file (i can export the VM...
  4. Very old server migration: virtio_blk needed?

    In every (linux) server I migrate from XenServer to PVE, i'll add virtio_blk and virtio_pci to initramfs and I'm using Virtio SCSI controller. For a very, very, very, very, very, very old server, (top performance is not a requirement) i have to migrate in the easiest way, so, if possible, to...
  5. [SOLVED] grub: invalid magic number

    Hi to all. I'm moving a lot of VMs from XenServer to Proxmox. I did this more or less 90-100 times before with my conversion script, every time worked properly EXCEPT for 1 VM. On the machine i'll add virtio_pci and virtio_blk modules to initramfs , then I install grub (if not already...
  6. Best way to backup VMs

    In our XenServer (cursed the day i choose to use that rubbish) node, we backup (sometimes) VMs directly exporting them from a snapshot. It's pretty useful because a restore can be mede directly, without resyncing a lot (millions) of small files. In Google Cloud, we do the same by only using...
  7. Expand pool

    Hi. I have to add 4 new SSDs disks to an existing RAIDZ2 pool. I'm not an ZFS expert and I don't want to loose/reduce redundancy making mistakes. Is this the right command to use ? # zpool add -n rpool raidz2 pci-0000:03:00.0-sas-phy4-lun-0 pci-0000:03:00.0-sas-phy5-lun-0...
  8. Upgrade from 5.2.2

    Hi to all. I have a 5.2 production server that i would like to upgrade to the latest version. Can I directly upgrade from the web interface ? Any additional steps? Should I upgrade to each version step-by-step or straight to the latest one ? I have to reduce downtime as much as possible. Just...

    Hi to all Current env: PVE 5.2-2 with 4 SSDs in RAIDZ-2 I would like to increase the available space by adding 4 disks more. What do you suggest ? Creating a new standalone RAIDZ-2 pool or grow the existing one to a new RAIDZ2 ? Is this something I can do from the web interface ? If not, as...
  10. Free space

    I have the following: # df -h Filesystem Size Used Avail Use% Mounted on udev 63G 0 63G 0% /dev tmpfs 13G 1.1G 12G 9% /run rpool/ROOT/pve-1 357G 3.1G 354G 1% / tmpfs 63G 37M 63G 1% /dev/shm tmpfs 5.0M 0...

  12. HW raid-6 to ZFS Raid1

    Stupid question, but I admit, I was never been able to measure IOPS and read/write throuhgput. I have a Xen node with 8x SAS 15k disks in hardware RAID-6 (512MB write cache) that I would like to replace with a Proxmox server. My idea is: can I replace this server with a new one by using ZFS...
  13. Bad disk usage report

    I'm using ZFS. In storage node, on the web interce, I see "local-zfs" and "local". Both are created over the same ZFS raid because i don't have any extra disk installed. The current visualization is messy bacause is showing that "local" has 44used over 395GB and "local-zfs" is 428GB/780...
  14. Replacement for Intel SSD DC S3610

    Seems that S3610 is EOL. intel told me that the proper replacement is S4600. I don't agree too much, because S3610 is MLC with high-endurance, 3.3DWPD, S4600 doesn't have that endurance and is TLC What is strange is that writes IOPS for S3610 are about 20.000, but on the S4600 are near 60.000...
  15. update without reboot

    What happens If I update the proxmox node but without the needed reboot (in a couple of days) ? I'm asking this due to ZFS, what happens by updating the userspace packages but still running with the older ZFS module (due to the missing reboot) ?
  16. novnc / xtermjs strangeness

    I have same strange issues with both terminals. novns is supposed to support window resizing, but when I resize the novnc windows, automatically is restored to the original size, thus, no resize is possible. additionally, novnc is still triggering a "noVNC encountered an error. Script error."...
  17. iothreads - how to backup?

    I need some clarifications: if I understood properly, in case of multiple disks connected to the same VM, iothreads is suggested because it uses 1 thread for each disks, right? Are multiple controllers a requirements? What do you mean with multiple controllers as wrote in docs? Do I need...
  18. Shrink a VM

    I'm migrating some VMs from XenServer to PVE. Now, one of these VM, has to be shrinked, if possible, in example, moving from 100GB to about 40GB. Is this possible ?
  19. Export running VM as backup

    Sorry for the dumb question but i'm new to proxmox, i'm using it from less than a year and with only 4 VMs currently. How can I export a running VM as a backup image, ready to be restored in case of disaster recovery ?
  20. SAS or SATA disks

    No, is not comparing a SAS 15k vs a SATA 7.2k disks. Most vendor, particularry HGST has both interface for the same mechanical disk. In example, 7K600 series comes with SAS or SATA interfce. It's the same disks, the only difference is the communication protocol. What do you suggest? SAS seems...
