No matter how I configure the /dev/sdb, after i format
the disk the sun disklabel is gone. Here is the steps I
used to create and verify the issue. Note: This does
not happen with ext2/ext3 file systems.
First - I create the disk label, doing this on a
secondary drive. This is Sparc system.
SCSI device sdb: drive cache: write through w/ FUA
sdb: sdb1 sdb2 sdb3
Second - Format /dev/sdb1 with jfs
mkfs.jfs version 1.1.11, 05-Jun-2006
Warning! All data on device /dev/sdb1 will be lost!
Continue? (Y/N) Y
Format completed successfully.
17635328 kilobytes total disk space.
Third re-run fdisk to verify disklabel
Device contains neither a valid DOS partition table,
nor Sun, SGI or OSF disklabel
Building a new sun disklabel. Changes will remain in
until you decide to write them. After that, of course,
content won't be recoverable.
