Re: Intel x540T on linux 5.2 :(

you need to beware of things like PCIe compatibility. Early PCIe cards were 5V and later were 3.3V and I suspect 2008 means PCIe 1.0 though I didn't look to check. I checked, the board is X9DR3-F , which is PCIe 3.0 , so this at least is ruled out I recall being able to get intel 10Gb/s to work on ...

Re: Intel x540T on linux 5.2 :(

Thanks, I will check in a different slot

And yes, I understand how outdated the system is and it's vulnerabilities, it will be used in a bit of isolated environment, without internet connection

Re: Intel x540T on linux 5.2 :(

Thanks

It didn't show up properly before installing the driver

Does showing up in lsmod and lshw give some hope it may work ?

Is your xfs filesystem on an LVM Logical Volume?
Nope, it is on a LUN made from a raid combining 12 drives in a raid 6 setup.

Snapshots on XFS

Dear

I have a server with an XFS volume, and is required to enable snapshot or a snapshot-like kind of backup on it.

The volume has to stays as XFS or ext3 , can't be brtfs nor zfs

Is there's a way or a 3rd party tool that can sync/backup in a snapshot-like manner ?

Any advice is appreciated

No, I don't have access to the second server I was using as a client anymore, however I'm quite satisfied with what I got from NFS so far Now I n...

Re: NFS speed on 10Gb/s RJ45

NFS v4.1 suppprts threads, so give a try with more threads. I think that the configuration file was '/etc/sysconfig/nfs' Thanks, I've tried increasing the threads from 8 ( the default ) to 16 , but still getting similar A single thread increased from 470 to 515 MB/s , while for 2 and 4 threads it a...
