btrfs balancing preparation
asked 2015-05-08 14:03:37 +0300
Hello, my phone has the BTRFS disease, it's totally out of space. This caused the 1.1.4 update to fail badly, I can't use the GUI anymore and I'm stuck with ssh access. Apparently, to prepare for performing the balance operation, I need to clear as much space as possible.
However, what meager knowledge of the Linux command line I have will only get me so far in tracking down the largest space hogs and efficiently getting rid of them. Could I get some command line help from the pros for
- quickly finding largest and unneeded files and
- deleting them in bulk wherever possible?
Otherwise this will literally take me weeks to get done, and it'd be quicker and less effort to send it in for repair.
EDIT: Now I performed the balance operations twice, and apparently after the 2nd one I have less space left than after the first, is that normal?

Do you have any important files in the phone? If so, you can copy some of them to your pc using ssh or to the sdcard. For sure you can recover the backups you created and the contacts (there is an all.vcf file in your home folder) but I don't know much more about sailfish, sorry.

Best as devel-su and from the root directory.
