Asymmetric Disk I/O priorities in a RAIDframe RAID1?

[Hauke Fath <hf%spg.tu-darmstadt.de@localhost>]

All,

is there a way in RAIDframe to give a member of a RAID1 set read 
priority, to e.g. favour reads from an SSD over rotating rust or iscsi?

The Linux mdadm(8) software raid config tool has the following option:


"[...] devices listed in a --build, --create, or --add command will be 
flagged as 'write-mostly'. This is valid for RAID1 only and means that 
the 'md' driver will avoid reading from these devices if at all 
possible. This can be useful if mirroring over a slow link."


Can RAIDframe do anything similar?

Cheerio,
hauke
