Not long ago we moved our VMs (about 50) to two Synology FS6400’s with 24 1.92 Seagate Ironwolf SSDs each. Both are split into two 11 disk (1 spare) RAIDF1 volumes and we use NFS 3 to connect the shares.
Speeds are great and everything is blazing fast… except for the few VMs that run Centos with XFS as the filesystem.
It’s seems there are some known issues with XFS on older Linux kernels, but this seems ridiculous. For example moving a VM from one store to another, a Windows VM with the same size NTFS filesystem moves nearly 50 times faster.
Does anyone have any tips?
