  1. UPS recommendation for proxmox host

    Follow up for those interested - I bought a rack.mount APC unit. The linux software they provide works perfectly well with PM 4.x/Debian 8. I've been able to configure it to shutdown all of the VM gracefully after 10 minutes of running on battery. Works great! Too bad CyberPower wasn't able...
  2. UPS recommendation for proxmox host

    I'm going off of other suggestions to not use APC, ever since Schneider Electric bought them out. But I've got nothing to really go off as far as hard evidence. I'm still open for suggestions. I've looked through the NUT documentation - it looks really complicated and overbearing. Plus it...
  3. UPS recommendation for proxmox host

    For what it's worth - I DO NOT suggest CyberPower. After a bunch of rigamarole, I found through their tech support that the Linux software they have will not work with Debian Jessie/8. They actually had the gall to recommend that I revert back to Debian 7. There is nothing in their...
  4. Syncing just one virtual hard drive

    I'm using PVE-ZSYNC successfully in a hot/cold availability situation. I've got a situation that would call for a VM to only have one of the hard drives to be synced between two servers instead of the entire VM. I don't believe that is possible with PVE-ZSYNC, but are there any other...
  5. RAID on ProLian DL320e Gen8 V2

    I have a few DL380 G7, so I'm going to presume that the built-in RAID controller has no option for JBOD, like mine. You've got two options for RAID on these HP blades when using Proxmox/Debian - 1) Set each drive to be a single RAID 0 on the controller so that the OS will see each one, and...
  6. PVE-ZSYNC what does the 'dataset is busy' mean

    Here is the body of the email - COMMAND: ssh root@xxx.xxx.xxx.xxx -- zfs send -i CTUPool/vm-disks/vm-104-disk-1@rep_VM104_2016-07-20_06:30:21 -- CTUPool/vm-disks/vm-104-disk-1@rep_VM104_2016-07-20_06:45:02 | zfs recv -F -- CTUPool/vm-disks/vm-104-disk-1 GET ERROR: cannot receive...
  7. Emergency help needed upgrading obsolete 1.8

    Much the same as what tom had mentioned - instead of upgrading, could you just make backups of all of the VMs on an external drive, install the new version from scratch, and then restore the backups? That's what I did to go from v3 to v4 MUCH easier. You have to absolutely make sure that the...
  8. Suggestions on 2 node HA

    Yea, having a fiber NAS/SAS was just not going to happen for me because of my university's unwillingness to run fibre in buildings, but between buildings, yes. Some use cases would be fine with a 1gb Ethernet connection, but not for a busy databases:confused: The 15 minutes is the default...
  9. Suggestions on 2 node HA

    Simply put - you're not going to get HA from 2 nodes. What fabian suggests is what I'm using, as I've got a similar situation as yours. No need to restore from a backup - just start the already existing VM on the other server. Very easy and quick recovery with a cold standby. The downtime...
  10. PVE-ZSYNC what does the 'dataset is busy' mean

    I've successfully setup PVE-zsync across 2 systems and turned the email notifications on. On what seems to be at random times, I get email messages stating that cannot receive incremental stream:dataset is busy It will successfully sync the next go-round. Since this appears to be a...
  11. SSD HW Raid 10 or ZFS Raid 10 SSD

    I haven't done any comparison testing with the syncing option, but I can say that there is a dramatic difference overall if you use the cache and log option in ZFS. I have a single SSD that I use for the boot/OS and created a 8G partition for log and 32G for cache on it as well. 32G of cache...

  13. General advice needed about clustering, HA

    To anyone reading this - This actually has already been covered in another thread that I didn't see at the time - https://forum.proxmox.com/threads/implement-backup-pve-server-without-shared-storage-using-pve-zsync.24997 This pve-zsync function is a great tool to setup a 2 server hot-cold...
  14. Proxmox VE Training 2020

    That might work out holding it in Toronto. I'm close enough to the border to make this work. I'll have to renew my visa, but I don't see any issues with it. One of the vendors that provided the training, StackTrace, is looking into the possibility of broadcasting the live training over the...
  15. pve-zsync failes on restored lxc

    I can replicate this issue as well. hammurabi's solution works for me, although the .conf file was located in a different location, and I had to remove "file=" instead, but it worked to correct the issue just the same. The more I use this pve-zsync function, the more I'm impressed with it...
