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, mkswap 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. Does anyone have an idea of what's going wrong here? -- J. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
