Question:
I am trying to implement fault tolerance on a Compaq Deskpro with two
325 MB hard disk drives. When I run FTSETUP to mirror drive D, I get
the error message, "There is not enough disk space to mirror drive."
My first hard disk drive (logical drive C) has a boot partition of 80
MB and an extended partition (logical drive D) of 245 MB. The second
hard disk drive has been partitioned the same way (logical drive E of
80 MB and logical drive F of 245 MB). Both hard disk drives are
straight HPFS and, other than OS/2 and OS/2 LAN Manager on drive C,
there is nothing else on the hard disk drives. Why is this error
message displayed?
Response:
Mirrored partitions are created in the UNUSED space of the extended
partition on the second drive. Logical drives take up space, so
FTSETUP was unable to set up a mirrored drive. To correctly install
fault tolerance at this point, you need to delete the logical drive
and try the mirror operation again.
Several other potential reasons for this error message are listed
below:
1. Attempting to mirror the boot partition
You cannot mirror the boot partition.
2. Attempting to mirror on the same drive
Drive mirroring can only be performed on a computer with two hard
disks.
3. Not enough extended partition space on the mirroring drive
Use FTSETUP or the PM fixed disk utility (FDISK) to delete the disk
partition.
