 |
|
Hello,
I enabled zram swap as per the wiki, and it's working fine 
But as I have already have a swap partition, how to ensure both are used if needed ?
I mean,
| Code: | swapon --show
NAME TYPE SIZE USED PRIO
/dev/sda2 partition 512M 0B -2
/dev/zram0 partition 512M 0B 16383
|
but I'm very sure the sda2 is used, as in TOP, only 1Go is displayed.
| Code: | top - 16:05:44 up 11 min, 1 user, load average: 1,01, 0,99, 0,66
Tâches: 200 total, 1 en cours, 199 en veille, 0 arrêté, 0 zombie
%Cpu(s): 4,8 ut, 1,4 sy, 0,0 ni, 93,8 id, 0,0 wa, 0,0 hi, 0,0 si, 0,0 st
MiB Mem : 7880,0 total, 6119,6 libr, 1025,9 util, 734,5 tamp/cache
MiB Éch : 1024,0 total, 1024,0 libr, 0,0 util. 6574,5 dispo Mem
|
If not, how to enable it as 2nd swap device ?
Thanks |

I am using "zswap" instead "zram" + using dinamic "swapspace" instead fixed swap partition, IMHO it better and clever.

destroyedlolo,
Multiple swap spaces are used in priority order.
I don't know which has the highest priority though. Highest or lowest number.

I didn't know about zswap but seems better on my boxes where I have swap on HDD.
I'll keep zram for /tmp and /var/tmp and ... swap only on system I don't want the "disk" to be stressed as on my SBC.

As per my reading, highest priority first.
So, as both are present in /proc/swaps it means both are usable.
I guess I found a good comparison here. |

It is, e.g | Code: | $ swapon -s
Filename Type Size Used Priority
/dev/zd0 partition 8388604 0 -2
/dev/zram0 partition 8388604 0 10 |
