Re: disk partitions on that aren't recognized by mkfs + parted



Ok, so things look fine till here when you have created partitions
sdh1,sdi1,sdj1,sdk1.. even after running partprobe if you are getting the
same here then try the follwing;

# delete one of the partition through fdisk eg.sdi1
# after deletion check eg. # fdisk /dev/sdi and then list the partitions
(You should not see anything)
# Recreate the partition as primary
#  Partprobe
# and then try mke2fs -j /dev/sdi1

Hope this should give some useful results.

Regards,

Raj
