I'm trying to familiarize myself with problematic ceph situations.
I can't find the solution to a situation that seems simple enough.
The problem is this:
Once I have inserted various OSDs I delete them, by Stop -> Out -> Destroy.
Now I try to add them again.
The problem is that the re-added...
If you intend modify the file /etc/default/grub like this:
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

So the most likely thing is that the SAS card is not compatible with the driver (in the particular case ULT3580-HH8).

I have a PBS server 2.4-1 that I'm trying to connect to a TAPE.
This is why I purchased a SAS card, specifically the SAS Adaptor ASA-70165H.
The TAPE is a TS4300
The TAPE is already connected to another server running Veeam.
The TAPE works normally with the Veeam system, the cables work, the...
Totally missed that page.
I used the "Routed Setup (Simple)" approach.
Note that multicast is not possible with this method
Can you explain to me what the downsides of this are?
We are thinking of buying a high-density server with four nodes.
I would like to create a ceph cluster without having a switch.
The idea is to connect all the nodes to each other.
In the specific case with 25Gbits connections.
However, with a test system I can't get the system to work.
The...
The server runs without problems.
All activities cause no problems.
Maybe I solved it, the problem seems to be that the influx server to which it sent the metrics had crashed, once reactivated everything seems to have returned to normal.
In my PBS installation (2.4-1) I have this situation:
I tried restarting but it didn't work.
How can I solve it?
the solution in this case:
https://forum.proxmox.com/threads/gap-in-the-graphs.135880/post-601516
Usually the solution is to set as host as CPU or create a new virtual CPU by enabling the avx and avx2 flag (but this last solution never worked for me), but the processor you have doesn't have AVX instructions, I don't think you can virtualize them.
In the same sperit of this post, where can I check the files (in this case the disk images) present in the BTRFS filesystem?
In this case the total space reported by proxmox i 6.02TB,
If i run the command btrfs filesystem usage /BTRFS i get 5.65TiB = 6,21TB.

I think I've found a better solution.
In the screen initramfs insert:
mount -o degraded /dev/sda3 /root -t btrfs
Where "/dev/sda3" is the healthy disck.
And press Ctrl-D.
For non-boot disks in the proxmox shell enter:
mount -o degraded /dev/nvme0n1 /BTRFS
Where "/dev/nvme0n1" is the healthy...
I followed this guide to temporarily change the GRUB.
The change was to add
rootflags=degraded
to the end of the line starting with linux.
This made it possible to overcome the problem of boot disks.
EDIT:
There is a strange thing, or rather (in my opinion) wrong.
Reported BTRFS volume capacity...
