Initrd-based Dump Saving
|
||||
========================
|
||||
|
||||
The problem with the procedure mentioned above is that your root file
|
||||
system (or whatever partition your KDUMP_SAVEDIR is in) may be corrupted.
|
||||
So the script may not be able to mount the device and is not able to
|
||||
save your file to disk.
|
||||
|
||||
For this, you can configure KDUMP_DUMPDEV to point to an unused partition
|
||||
that is large enough -- i.e. larger than the system's main memory -- to
|
||||
hold the dump. Before mounting the root file system, the init script
|
||||
writes the dump to that device. After rebooting, the normal boot script
|
||||
saves the dump from that device to KDUMP_SAVEDIR. Because the data was
|
||||
is saved to disk, you can safely turn off the computer and/or repair
|
||||
the file system using some tool (for example, you may need to boot from
|
||||
a CD which is no problem).
|
||||
|
||||
After you changed that value, you have to re-run mkinitrd on the kdump
|
||||
kernel, or on all kernels.
