I am getting the following error when writing:
=================================================
Disk /dev/hdb1: 8447 MB, 8447330304 bytes
16 heads, 63 sectors/track, 16367 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Device Boot Start End Blocks
Id System
/dev/hdb1p1 1 16367 8248936+
8e Linux LVM
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with
error 22: Invalid argument.
The kernel still uses the old table.
The new table will be used at the next reboot.
Syncing disks.
=================================================
After I reboot, I still see the old format. What am I
missing?
Thanks,
Charles Li
