If you put it onto the nic that is assigned to vmbr? - I think that only the communication between host<->vm will not work. - But the host should be still reachable from anything else, and VM's should have no issues either. - Example: auto eno1 iface eno1 inet static address...

PS: i forgot to mention. FSYNCS/SECOND: 909.08 -> is not really bad, looks okay to me for lets say 4SSD's in Raid 10. FSYNCS/SECOND: 2932.92 -> For 6x 10k SAS-Disks, looks far too much to me, like it's just a cached result. Maybe we should start with that. Because i get: CPU BOGOMIPS...

Check if there is a multiplexer card, if there is, remove it if possible. Check if you can use HBA mode somehow, firmware updates for the raid controller helps often. In my particular case, i need an Raid-Card for the old esxi servers, either a raid card or an iscsi/fs storage, because its esxi...

Mach mal Hacken bei Firewall raus. Nichts destotrotz denke ich eher das das was mit unraid zutun hat.

Der ESXI-Import Wizard, ist lahm das stimmt. Nicht destotrotz hab ich mit dem ungefähr 20 VM's migriert über ein Wochenende. Sind so 8TB an Daten insgesamt. Also gings doch trotz ersteindruck relativ schnell, was mir aufgefallen ist, das manche VM's lahm migrieren, andere wiederum schnell, das...

Thats a good advice! Shutdown/poweroff/start fixed some nvme issues i had in the past either with consumer nvme drives.

The keyboard still works... i would boot the machine simply, blindly type root and your password, enter and then: insmod r8125 systemctl restart networking Then you should get ssh access again :)

dd if=/dev/zero of=/root/zeroes bs=$((1024*1024)); rm -f /root/zeroes fstrim -v / Wait then 5 Minutes or so and reboot once, just to get sure and check with smartctl again :) It has only 778GB Written, that SSD is basically brand new, lol

TBH, They are all very Hot, no matter which Raid-Card i seen in my life. So i wouldn't worry at all about the heat. Maybe True HBA-Cards are Cold, but even the 9305 that i use now with IT-FW is very hot. Not sure about those new Broadcom Tri-Mode Controllers, since they are too expensive to test xD

Just a note, on my Backupserver (ML350 G9), that has 24 3,5inch bays, was some sort of HP-Raid Controller, with a Multiplexer built in. I dont remember which controller it was, but one that comes as default with ML350 G9. And both ZFS-Pools (One Consists of 12x 4TB Sata drives, the other...

15gb/s is a bit low for 2 containers on the same node and same network. Very low, i reach on lowend e5 v3, extremely old xeons, at least 30gb/s per core/stream

People are talking here about saving Power :) Im more in search of more performance, but more performance also means that the CPU doesn't get too hot. So is there anyone already with Epyc Milan/Rome/Genoa Servers out here and can report if its worth it over acpi? I thought of using...

Lets do it differently, i think you dont care about sync writes or parallelism things etc. I think you want simply better performance. There is indeed a performance issue with ZVOL's (every VM on your ZFS Storage) is using Zvol. Except if you defined a storage as "Directory" on the ZFS Pool...

Did anyone with kernel crashes, tryed to disable Hyperthreading? I have no kernel crashes here, but issues related to the scheduler, its not working how it should (i think). Still debugging the issue. But my issue is definitively related to HT, because everything that runs on HT-Cores has only...

the "fix" was merged into 2.2.4 https://github.com/openzfs/zfs/pull/16098 But all the original PR is doing as far i understand is just using multithreading for that issue. Its not fixing ZVOL's main issue with the caches. However, as far i understand people should see at least an improvement...

There is no difference and it has anyway nothing with iperf itself todo. You can do parallel with iperf2 and 3, there is no difference, but im not talking about parallel. Im talking about something in vmbridge or kernel or ip stack in the kernel, that is sometimes multithreaded and sometimes...

Hi, is it possible to use PMG to Route incoming Mails based on their destination mail address, to specific Mailservers? Thats called in German a "Mailweiche", but im not sure how it's called in English. The usecase is very simple, for example you have two companies that merged together, but...
