Hi,
I have 3 swap devices and files. At boot, it seems indeterminate which
ones get "mounted" (as swap areas).
Does anyone have an idea why they're not all mounted?
Here are the swap lines from my fstab:
#LABEL=swap none swap sw 0 0
/dev/disk/by-id/ata-TOSHIBA_DT01ACA300_xxxxxxxx-part1 none swap
sw,pri=10 0 0
/swap none swap sw,pri=5 0 0
/lcl/WDC_WD20EFRX-68EUZN0_WD-yyyyyyyyyy/1/swap none swap
sw,pri=1 0 0
The second entry is missing the device you intend to mount.
When you list the first and third devices do you see anything wrong with them?
When you try to enable them manually with 'swapon -v' what do you get?
PS. If any of these swap block devices are actually files within a fs make
sure you first fill them up with dd, because files with holes in them could
fail to be enabled. Also some fs (btrfs?) are not good candidates for having
swap files on them, if they move data around with cow.
The second and third entries are files, created with dd(1), from
/dev/zeros, as shown on the mkswap(8) man page. No word in
/var/log/messages for non-mounted swaps.
