- add `zramSwap.algorithm` option, which allows to change compressor declaratively. zstd as default - add `zramSwap.swapDevices` option, which allows to define how many zram devices will be used as swap. Rest devices can be managed freely - simpler floating calculations - fix udev race condition - some documentation changes - replaced `/sys/block/zram*` handling with `zramctl`, because I had occasional "Device is busy" error (looks like zram has to be configured in predefined order) - added `memoryPercent` and `algorithm` as restart triggers. I think, it was a bug that changing `memoryPercent` in configuration wasn't applied immediately. - removed a bind to .swap device. While it looks natural (when swap device goes off, so should zram device), it wasn't implemented properly. This caused problems with swapon/swapoff: ``` $ cat /proc/swaps Filename Type Size Used Priority /dev/zram0 partition 8166024 0 -2 /var/swapfile file 5119996 5120 1 $ sudo swapoff -a $ sudo swapon -a swapon: /dev/zram0: read swap header failed $ cat /proc/swaps Filename Type Size Used Priority /var/swapfile file 5119996 0 1 ``` |
