I just switched my desktop FC5 system from using software RAID over regular
partitions to using software RAID over LVM; everything works fine, except
I can't enable my swap.
On boot, I get the following messages:
device-mapper: device 9:1 too small for target
device-mapper: dm-linear: Device lookup failed
device-mapper: error adding target to table
.
.
.
Unable to find swap-space signature
My swap volume is listed like this in my /etc/fstab:
/dev/VolGroup00/LogVol01 swap swap defaults 0 0
If I try to format the swap volume, it tells me that it's too small:
# mkswap /dev/mapper/VolGroup00-LogVol01
mkswap: error: swap area needs to be at least 40kB
But 'lvm lvs' reports that's it's 1GB:
LogVol01 VolGroup00 -wi-d- 1.00G
I've tried deleting and recreating the swap volume:
# lvm lvremove VolGroup00/LogVol01
# lvm lvcreate -L 1024M -n LogVol01 VolGroup00
device-mapper: reload ioctl failed: Invalid argument
Failed to activate new LV.
What's going wrong here?
