Hi all,
i've been using raid1 sisnce quite a loto of time. Sporadiccaly an array
fails a disk and in many situations I can just pull the device into the
array with
mdadm /dev/mdN --add failded_device
I've never really understood what is the magic that resurrexes it. I
thought something related to relocation of bad blocks, but I'm not at
all aware of what happens "there"...
Is that a correct trial to do?
Now I have a device that throuws an error:
srv-ornago:/tmp# mdadm /dev/md2 --add /dev/hdc6
mdadm: hot add failed for /dev/hdc6: Invalid argument
the kernel complains:
Mar 1 09:34:29 srv-ornago kernel: md: could not bd_claim hdc6.
Mar 1 09:34:29 srv-ornago kernel: md: error, md_import_device() returned -16
is this enought to say the disk (pretty new, 6 months) is to be changed?
which checks should I do.
Thanks in advance
