4.9.3.2 Setting a label for the dump saving area
Use the e2label command to set a label for the area to which a dump is to be saved.
# e2label /dev/sdb2 /dump
# e2label /dev/sdb2
/dump
4.9.3.3 Setting up the dump environment
Edit /etc/kdump.conf to specify the area to which a dump is to be saved. Also, make
settings for the dump function and others. The setting procedure is explained using a
definition example below. Code the parts, which are not explained, as indicated in the
definition example.
ext3 LABEL=/dump
path /
core_collector makedumpfile
default reboot
~~~~~~~~~~~~~~(2)
1
Set /dump and the label for the area to which the dump is to be collected, and
define the label as the dump saving area.
2
Specify reboot for the operation to be performed after dump collection. If
sadump has been applied, the sadump definition is followed after kdump
collection, and therefore the values set here are ignored.
core_collector makedumpfile -c -d 3
3
Specify this to use the compressed dump function. Omit it if the function is not
used. The compressed dump function can reduce the dump collection area but
may take more time for dump collection. Perform performance verification
sufficiently before enabling the compressed dump function.
4 Specify this to use the partial dump function. Omit it if the function is not used.
Also, add the following definition to KDUMP_COMMANDLINE_APPEND of
/etc/sysconfig/kdump.
swiotlb=128
If /etc/kdump.conf is set again, the sadump service or system needs to be restarted.
