- jeffbee 3y agoOn Linux, XFS never offered guaranteed-rate I/O. It was really an IRIX feature that also required hardware support.
- T3OU-736 3y agoFun story. GRIO (Guaranteed Rate IO) XFS support was added to IRIX due to a request by a US Gov't agency. This agency was doing electronic signal collection with IRIX on SGI HW, and wanted to a way to guarantee that whatever their sensors captured would be written to the storage media, no matter what else is going on at the OS level.
