Hello,
i noticed this while twiddling with RAID1 arrays...
On our old CentOS 4.7 box, i can mount a RAID1 array member independently of the array -- i.e. mount /dev/sdc1 /mountpoint....but on CentOS 5.x and later i am met with an unknown filesystem: linux_raid_member error.
Somebody hinted that this had something to do with the metadata versions, so i recreated the RAID1 array on CentOS 5.x with the --metadata=0.90 parameter...and was able to mount the array member w/o any problems.
Is this expected behavior? Are there any potential problems if i stick with metadata=0.90(apart from the 28 device and 2Tb disk space limit)?
tia
