Noswap doen't work anymore

[benjibasson]

Hi
Since the february's update, the cheatcode noswap doesn't work anymore

expected result: no swap partition in use

Code: Select all

root@porteus:/home/guest# swapon 
NAME                    TYPE      SIZE USED PRIO
/dev/zram0              partition 3.3G   0B  100

what happen?

Code: Select all

root@porteus:/home/guest# swapon 
NAME                    TYPE      SIZE USED PRIO
/dev/sda6               partition 9.7G   0B   -2
/dev/zram0              partition 3.3G   0B  100

how to fix this? my /dev/sda6 is used to my Arch linux hibernation, and if other linux erase suspend data from /dev/sda6 it make extra mess in this distrib ( whole file system corruption)

Cheers

I'm not seeing what you're seeing benji.

Code: Select all

guest@porteus:~$ su
Password: 
root@porteus:/home/guest# swap
bash: swap: command not found
root@porteus:/home/guest# noswap
bash: noswap: command not found
root@porteus:/home/guest# swapon
root@porteus:/home/guest# swapon
root@porteus:/home/guest# swapon -s
root@porteus:/home/guest# 

I don't use the noswap cheatcode and I have no partitions formatted as swap. Why do you have swap partitions if you don't want them used?

Code: Select all

guest@porteus:~$ lsblk -f --output NAME,FSTYPE,LABEL,SIZE,TYPE

Since the february's update, the cheatcode noswap doesn't work anymore

can't seem to reproduce this.. ie. noswap works as expected here..
i did introduce a new cheatcode: "swapfile=" into /etc/rc.d/rc.S, but that shouldn't have any effect on the noswap cheatcode (in fact, it requires it if there is a swap partition present) because it should do nothing at all if it isn't being used..
are you using any other cheatcodes or something else in the booting process?

Hi,

@Ed_P
the swap partition is reserved for my arch Linux and its hibernation.
I prefer to use the swapfile on porteus via RC.LOCAL and change=

@ncmprhnsbl
I am using this boot option and it mont and swapon /dev/sda6 swap partitions

Code: Select all

menuentry "porteus  on sda3 xfce safe mode"{
set root=(hd0,3)
linux /porteus64bit_v50/boot/syslinux/vmlinuz from=/dev/sda3/porteus64bit_v50 load=999 resume=/dev/sda3 resume_offset=4268032 login=guest copy2ram ramsize=14% zram=43% noswap noauto
initrd /porteus64bit_v50/boot/syslinux/initrd.xz
}

even with

Code: Select all

menuentry "porteus  on sda3 xfce always fresh"{
set root=(hd0,3)
linux /porteus64bit_v50/boot/syslinux/vmlinuz from=/dev/sda3/porteus64bit_v50 login=guest copy2ram base_only noswap
initrd /porteus64bit_v50/boot/syslinux/initrd.xz
}

it swapon

Code: Select all

/dev/sda6               partition 9.7G   0B   -2

didn't occure with 20221210's update
always occure with 20230216/

ok, to rule out(or in) the change in /etc/rc.d/rc.S, since you're using changes, comment(#) or remove lines 62 to 83 in /etc/rc.d/rc.S (as root user)
although i don't see the changes= cheatcode in your examples..
otherwise, make a module with that adjusted file in it and place in your modules folder..
another thing to try is maybe using the swapfile=</path/to/swapfile> cheatcode instead of the rc.local way, to seee if that makes a difference (without the above change)
apart from this, i can't see how any of the package updates might be affecting this..

Should I remove both noswap and rc.local content to add swapfile=</path/to/swapfile> cheatcode?

The change is on 999-change.xzm on optional ( purpose switch off sda drive. And take less memory on ramsize with compressed change)
