I currently have 30Tb of dedup'ed backups on the running PBSs with dedup factors between 60 and 110 depending on the PBS. Considering a worst-case data growth of 20% each year we'd be reaching 76Tb of backups in 5 years. While 100Tb might be oversized, I do not think it is oversized by a lot. I...

Hey all, Continuing on my journey to create a somewhat good Proxmox Backup Server infrastructure for my company, I'm now considering different hard drives configuration, but am a total noob when it comes to high (for us) quantity storage. As of now, the idea would be to have around 100Tb of...

Hi, Thanks for your insight, datastore wise this is a good idea, and I'll follow up with it. Sync wise, I might be limited by disk space, but I agree with you that syncing to multiple PBS would be better.

Hey all, I've got the opportunity to upgrade the Proxmox backup servers running in our production environment. Currently, I have the PBS set up as follows : DC A backups to the PBS on DC B DC B backups to the PBS on DC A DC C backups to the PBS on DC A I am fully aware that this is not...

Bonjour, As you've stated, the linux kernel is the bottleneck, and solutions to this include XDP and DPDK. (I've also dabbled with VPP, though I must say the documentation is harder to understand for me). This hasn't been a priority for us, but I'm sure 10G routing on virtual machines will be...

Hey there. I marked it as solved because I didn't need help with my issue any more. Sorry if that was misleading. I'd recommend opening a new thread with your specific use case, as it seems to differ from mine. Best Regards

As I understand it, there's no way to create more than 65535 subfolders in a folder. File size doesn't matter. As for the loop mount, I've honestly got no idea, but seeing as how I get an IO error when manually creating a folder, I do not think the VNXE would allow it.

Alright, well, that's a shame. Guess I'll have to find another use for the VNXE. Thanks for the reply.

Hey all, I'm trying to use an old Dell VNXE Storage as a sync target for cold storage out of site backups copy. The datastore creation fails with an IO Output error. As it turns out, it seems I cannot create more than 65533 folders : root@definitelynotwhereiam-pbs2:/vnxe/.chunks# mkdir foo...

No dumps. Kdump works, I crashed the PVE on purpose a while back and it did create a dump. It's crashing hard : no keyboard input, black screen. No network, though I didn't check if there was network traffic on the switch after a crash. If it does crash again, I'll check it out. Afaik, the...

You know, at this point, I wouldn't put a memory speed issue in the silly category. I've set it to 2400MTs, It's an Intel Pentium Gold G6405 anyway, don't think that's going to make much of a difference. :D Will report back on the next crash or in a while.

Hello, I appreciate your patience with this. I have remote logs via rsyslog. I had tried running netconsole, but didn't get anything. It crashed again this morning. No logs, no nothing. I've just ordered usb thumb drives to burn a debian iso and see if I can get the same behaviour.

Hey, Yeah, after posting that, I saw the new 6.2 Kernel and switched to it. I will see if it does make a difference.

Hey all, It's me again. Something must have happened with the updates, and I feel I'm chasing ghosts at this point. A bit after my last message, I stopped getting crashes. Nothing else changed on the host. In fact, I started a minecraft server back in January, and everything had worked...

I didn't have time to check yet on if the DD6400 supports atime. On a general note, what would be the consequences of disabling GC on a PBS? Cheers

Documentation of the DD6400 mention using atime for its "locking" system, which basically protects files from being deleted (this feature isn't enabled on that specific NFS share) I'll go and check if I see anthing on the web interface, and I'll try switching the from relatime to atime on the...

This is the line if my fstab : theIP:/data/col1/shareName /mnt/dd6400 nfs defaults,user,auto,_netdev,bg,local_lock=all Here's the mount output for that share ...

Hey all, Foremost, I am aware that backups on NFS shares aren't the way to go. This is experimental, but I'd still like to share this issue. We're running a PBS that has an NFS Share on a Dell DD6400. As the PBS doesn't support the ddboost protocol, we're using the NFS feature to store...

Hey all. We figured it out. Turns out our CA system got updated, and in the process, the Signature algorithm got switched from SHA256 to SHA1. Here's a diff between OpenSSL outputs from a good & bad certificate : 68,69c68,69 < DNS:the domains :) < Signature Algorithm...

Hey all, I'm stumped on an issue, and at this point the only explanation I have is black magic. I have multiple PVEs on different sites. For backups, they all share a common layer2 VLAN. They all can see each other, and ping each other. SSH works, but SFTP / RSYNC fails between 3 specific...
