I have not been able to confirm if /proc/diskstats can report more than 32 bits.
I am pretty happy with FlopSwap now.

Therefore, I have pushed it to testing, please rate. Thanks

I have 4 partions on SD set up as so:

Code:
   Device Boot Start     End   #cyls    #blocks   Id  System
/dev/mmcblk1p1          0+  62499   62500-   1999992    c  W95 FAT32 (LBA)
/dev/mmcblk1p2      62500  200467  137968    4414976   83  Linux
/dev/mmcblk1p3     224882  249295   24414     781248   82  Linux swap / Solaris
/dev/mmcblk1p4     200468  224881   24414     781248   82  Linux swap / Solaris
FlopSwap doesn't seem able to see them. Is there something else I need to do to get them noticed?

I have discovered what the porblem was; even though I told cfdisk under easy debian to make the partions swap, I still had to run mkswap to get them ready. Have now done so and everything's tickety-boo.

Thanks for getting back to me Tom.

Anyway another bump, need a few more votes to push to Extras.

Flopswap can't check status for me:
Code:
$ sudo /opt/flopswap/script/swapused.sh 
/dev/mmcblk1p2 /dev/mmcblk0p3
/dev/mmcblk1p2 mmcblk0p3
sh: mmcblk0p3: unknown operand
sh: mmcblk0p3: unknown operand
sh: mmcblk0p3: unknown operand
and says check only one swap is active
Flopswap is enabled in settings.

/edit: but /dev/mmcblk0p3 seems not to get disabled. weird...
/edit2: and `sudo start relocateswap` returns 1

This is correct flopswap calculates swap used on the active swap, therefore only one must be active not two.

Good this is correct.
Have you setup two swap partitions on the uSD like in the wiki?
http://wiki.maemo.org/Flopswap#Partition_Requirements
http://wiki.maemo.org/Flopswap#FAQ

If you have issues after fixing your partitions and rebooting, please post output of
Code:
blkid | grep swap     -- ( need root)
dpkg-query -W -f='${Version}\n' upstart
dpkg-query -W -f='${Version}\n' flopswap
cat /etc/default/mount-opts-overwrite
cat /etc/default/mount-opts
cat /etc/fstab

I'm not sure whether they're equally sized, but their sizes are similar. But one of them is on eMMC, on of them on uSD. And I'd rather it stayed like this

Code:

/dev/mmcblk1p2: UUID="4ca89a73-e144-40a2-92ee-6f5d4722addb" TYPE="swap"

Nokia-N900:~# dpkg-query -W -f='${Version}\n' upstart
0.3.8-68+0cssu7
Nokia-N900:~# dpkg-query -W -f='${Version}\n' flopswap

Unfortunately flopswap needs and is designed purposely to use the two linux swap partitions on the card.

It doesn't have anywhere to flop to otherwise

It has the internal swap to flop there (it should be disabled normally and enabled only for defrag)...

Could you add floping main -> secondary -> main,
with main = uSD swap, secondary = internal swap in the next release?

That is how ereswap works not flopswap.
Flopswap doesn't do that it is purposely designed to not use the device swap at all.
Not only does it reduce eMMC wear, it also takes half the amount of time and effort to refresh the swap. This is the whole method behind "flopswap".
eMMC is only manually used so you can remove the back cover.
