Good plan for the first part. But I wouldn't get rid of the cheap
drives. They may lack features needed for best use in a raid array, but
they are fine for solo duties. I have some similarly annoying Seagate
drives. I use them one-by-one for off-site rotating backups.
this was my secound time to buy WD devices. i bought 5 harddisk from the
green series and all disks have very dangerous smart values. two devices
i send back within one year :(
my new server have segate drives and i have with segate rarely problems
over years and the performance is very good. i hope with this drives are
that same.

The partition structure on /dev/sdc is causing the array to be too short
for the filesystem. There are two possibilities:
1) The partition doesn't go far enough to the end of the disk,
For this, repartition /dev/sdc to start at sector 2048 and end at
3907029118. Then re-create the array, open luks, and do "fsck -n" and
show the results.
roger that.
i would do this:
parted /dev/sdc
unit s
resize 1 2048 3907029118
parted /dev/sdc unit s print -> to check my new settings
recreate the md2 device with chunk 512 and the order we find out.
open luks
check it with fsck -n and report you my (errors) result.
2) The partition starts too far into the disk (move start sector to 34
like sdb and sde).
For this, repartition /dev/sdc to start at 34 and end at 3907029118.
This makes it match sdb and sde. Then re-create the array, open luks,
and do "fsck -n" and show the results.
this is the next step if you say step one is the wrong one.
parted /dev/sdc
unit s
resize 1 34 3907029118
parted /dev/sdc1 unit s print -> to check my new settings
recreate the md2 device with chunk 512 and the order we find out.
open luks
check it with fsck -n and report you again my (errors) result.
ps. I hope this odyssey has emphasized to all lurkers how terrible it
can be to use "mdadm --create" without careful, thorough preparation.
@ ps: sorry that i do this and thx for your help!
You're welcome.
Phil
please verify my steps.
thx
