Experience with XFS

I have installed a SOBR with three extents of XFS in our largest VCC datacenter.  It works extremely well and have not had issues.  We did mix it with ReFS but that was a bad idea and created a new SOBR just for XFS alone and no mixing.

We also try to keep SOBRs at 2-3 extents maximum and then create new ones as needed.

Thanks Chris!

What was the problem(s) when mixing XFS with ReFS in a SOBR?

Just that XFS and ReFS did not play well together so it is best to have them separate.  Been rock solid since.

We’ve had ~30 Ubuntu 20.04 repo’s in production since v10 launch in 2020, all with reflink enabled; the majority being at client sites and then a few ~500TB extents in sobr’s at our data centers; they all have been rock solid, which is to be expected from linux.

  • stability - no issues at all
  • performance (over time) - hasn’t changed in a year; only limited by the disk iops available from your hardware
  • needs for troubleshooting - no troubleshooting over the past year
  • administrative effort - linux experience or being a fast learner is important for the initial design and deployment; hardware monitoring/testing to determine the number of concurrent jobs that your hardware can handle requires some effort in the beginning but that applies to any OS; after that, cron jobs take care of updates and we schedule a manual reboot of the repo’s whenever an update notifies us that it requires it

I have successfully tested XFS repos in a POC.

One of my customers wants to exchange Windows repos with Linux.

Immutability flag is the most convincing argument.

No experiences on large scale just some tests on old storage array, works pretty well.

I’m excited to build a large (many PB+ ) SOF xfs based, 2021 will be fun! :nerd:

Thanks for sharing interesting links @vNote42 , from my pov XFS/Reflink is more old and stable than reFs when it appears.

It is true for a while the refs driver was buggy :(

I had tried to set up XFS as a Veeam repository and failed. No real help from the support either and I had to settle with NFS based repository. But this was with v10.

Thanks for the information @gulzarshaikhveeam. What did not work?

It used to fail to get added as a repository. The support tried various steps but it did not work ATT. Case # 04450930

Not yet, but I have a few customers VERY interested and will be testing soon with them. I will update here.

actually no one has any experiences with XFS as Veeam repository to share?
