# Configuration settings for kdump/pstore. After _any_ change in this

# Pstore-RAM settings
|
|
# If USE_PSTORE_RAM is set to 1, Kdump won't be loaded. Instead, the Pstore
|
|
# RAM backend will be configured. In order to have success, this operation
|
|
# relies in having an available RAM buffer on /proc/iomem with at least
|
|
# PSTORE_MEM_AMOUNT (decimal, in MB) in size. Also, kernel must be able to
|
|
# allocate a contiguous memory amount of PSTORE_RECORD_SZ (decimal, MB).

# MOUNT_FOLDER is the the place in which both pstore and kdump logs will

# be stored, as well as the kdump initrd and some ancillary data. This

# Currently we only do local storage log collection (no network/iscsi dumps).

# If FULL_COREDUMP is !=0, we collect a full compressed vmcore, which might
|
|
# require a lot of disk space. The MAKEDUMPFILE_*_CMD settings refer to
|
|
# tunings on makedumpfile - we rely on zstd compression and maximum page
|
|
# exclusion for the full vmcore, mimic'ing Debian/Ubuntu kdump. We also
|
|
# base on Debian/Ubuntu for the KDUMP_CMDLINE_APPEND option - this contains
|
|
# the kernel parameters we append in the /proc/cmdline for the kdump kernel;
|
|
# the most important parameters are nr_cpus=1 (to save RAM memory usage and
|
|
# avoid some potential issues with SMP) and reset_devices (some drivers
|
|
# rely on that for proper kdump).

# GRUB-related settings

|
# GRUB_AUTOSET determines if the kdumpst loader tool should try to
|
|
# automatically set grub.cfg in order to reserve memory for kdump (if
|
|
# needed, i.e., when pstore is not in use) - keep it as '1' for enabling
|
|
# the mechanism (this is the default). GRUB_BOOT_FILE is the full path of
|
|
# grub.cfg file - this is used in the config update step plus for syncing
|
|
# purposes. GRUB_CFG_FILE is the config file we edit in order to add/remove
|
|
# the crashkernel parameter. Finally, GRUB_CMDLINE holds the change to be
|
|
# made in the grub config file, specially the crashkernel memory reservation
|
|
# (notice that a trailing space is required in this line, so we avoid
|
|
# messing with other kernel parameters).
