 |
|
hi .
on my low ram (2gb) system i would like to try the example in gentoos wiki :
| Code: |
load_on_start="yes"
unload_on_stop="yes"
num_devices="3"
type0="swap"
flag0=
size0="4096"
maxs0=2
algo0=lz4
type1="/tmp"
flag1="ext4"
opts1="noatime"
mode1=777
size1="1024"
labl1="zram-tmp"
type2=/var/tmp/portage
flag2=ext4
opts2="noatime"
size2=8192
algo2=zstd
owgr2="portage:portage"
mode2=775
labl2=zram-var-tmp-portage
back2=/dev/mapper/zram-nvme0n1p4
icmp2=y
idle2=600
|
but i dont know how to set up the type2 . i have created a new zram-init file with ^ this ,created new partitions for type 1 and 2 . but getting :
| Code: |
myt100 /home/hedmo # /etc/init.d/zram-init start
* Loading zram module... [ ok ]
* Swap->zram0 [ ok ]
* Mount zram1 /tmp
mke2fs 1.47.0 (5-Feb-2023) [ ok ]
* Mount zram2 /var/tmp/portage
/sbin/zram-init: line 72: printf: write error: No such file or directory
zram-init:
Warning:
zram-init:
failed to set zram2 backing_dev
/sbin/zram-init: line 72: printf: write error: No such device
zram-init:
Warning:
zram-init:
failed to set zram2 incompressible writeback
mke2fs 1.47.0 (5-Feb-2023) [ ok ]
myt100 /home/hedmo #

Not sure if this is going to help, but my zram config for /tmp/var/portage looks like this (mine is type0 instead of type2)
| Code: | type0=/var/tmp/portage
flag0=ext4
size0=24576
mlim0= # no hard memory limit
back0= # no backup device
opts0="nosuid,nodev,noatime,discard" # e.g. "relatime" or "noatime" are also reasonable choices
mode0=1777
owgr0= # No reason to change the default "root:root"
notr0= # keep the default on linux-3.15 or newer
maxs0=12
algo0=zstd
labl0=tmp_dir
uuid0=
args0= |
I have no backup device, which seems to cause problems for you. Also is not clear what is line 72 in your config.
