Hi
I am running SUSE Linux Enterprise Server 15 SP1" on a test server to check the SAP installation.
it was running fine, all of sudden it is getting restarting starting some days back exactly at midnight 00:00:00 hours.
it getting restarted mostly every 2 or 3 days but must on Sunday midnight.
after restart i did able to check what caused. no crontab file exists for any user.
but i did see it creating around 5 to 7GB of crash file at /var/crash/*
i ignored as it is my test system. but now… system is not able to start and hangs at first boot screen.(splash Screen)
i guess /var/crash is filled up. and that is the reason / file system also got 100%.
i have below questions:
how can i clear the file system of (crash dump)…
how to login to system using a single user mode for SUSE 15 SP1?
Thanks in Advance

Hi
You have a grub option to enter rescue mode, or even failsafe mode. Else boot from the install medium and get to rescue mode. You should then be able to mount/clean the file system as required.
Login in maintenance mode is root user and password…

Hi malcolmlewis
i am able to rescue login, by pendrive login…but not able to mount:
cd /dev
ls -ltr
i can see sda1 sda2 and so many folders…
tty1:rescue:/dev # cd sda2
bash: cd: sda1: not a directory
tty1:rescue:/dev # mount /dev/sda2 /mnt
unknown file system type ‘LVM2_member’.
mkdir /xyz
mount /dev/sda2 /xyz
/xyz: unknown file system type ‘LLVM2_member’.
mount /dev/sda1 /xyz
wrong fs type, bad option superblock /dev/sda1, missing codepage or helper program,or other error
mount /dev/sda2 /xyz
/mnt: unknown file system type ‘LLVM2_member’.
if i sudo some command it says sudo commnad not found.
Thanks in advance
Hi
So your using lvm, so you need to mount the volume group etc
https://documentation.suse.com/sles/15-SP1/html/SLES-all/cha-lvm.html#sec-lvm-cli
Do you see output from;
lvdisplay
lvs
You should already be root user, no need for sudo far better to switch to root user with su - unless you have properly configured sudoers file…
