Does anyone have experience with compressing core dumps before they are written to disc? A vendor wants core dumps for a certain problem with their program, but it makes large core dumps (over 100MB), so I want to reduce writes to storage as well as download times.
First, I made a script as /wfs/core.sh:
/usr/bin/xz -1 > /wfs/user/core.xz
Then a boot command:
/bin/echo “user soft core unlimited” >> /etc/security/limits.conf
/bin/echo “user hard core unlimited” >> /etc/security/limits.conf
/bin/echo ” | /wfs/core.sh” > /proc/sys/kernel/core_pattern
and finally a custom application:
pkill -11 programname
However, it is not making the core dump, and I see no errors in the logs. Does anyone have any ideas?
Using ‘/bin/echo “/tmp/core” > /proc/sys/kernel/core_pattern’ and compressing the file from there worked well enough.
Great! I wasn‘t able to test your procedure until now. Just a hint: using the Custom Partition feature itself (System=>Firmware Customization=>Custom Partition=>Partition) would create a persistent RW partition. The size could be 1-2Gb if needed and be set up as target for your script. wfs idn‘t really meant for that
