Hey all, I'm seeing a weird behaviour on one of my PBS node. The GUI verify job which should run every day has been failing for a few days now. Upon further investigation, the verify job is trying to verify a non-existent (probably pruned) backup : (datastore name has been censored but isn't...

To be fair the main bottleneck in our current setup is definitely the PBS. If, one day, the main bottleneck is the network, I'll be a happy man. Dell public prices are dumb. They get better if you have a business relationship with them, but they still get you on the ram and storage. Reckon we...

We do indeed have dark fibers between each DC. Its a 10G loop except for DC4 which has 500M. I believe there's a misunderstanding here. This is my fault, and I haven't precise enough. The backup size I stated earlier is on disk size. Nightly volume is between 100G to 200G. This doesn't make...

I'd very much like help on this, as my experience with ZFS never left the homelab. I agree with you that hardware raid is bad. Furthermore, I'd also like to use ZFS, but I need a solid understanding of it first, so I can be sure that when a drive eventually dies, either me or someone else with...

Alright, thanks for your input. I'm going to reassess and consider using "tiering" for my PBSs : SSD only "Primary" PBSs for short & medium term backups, and RAID6 HDD only PBSs for long-term storage. This might not be the most optimal way of doing it, but it sure is going to be much better than...

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
