-Which process is writing to disk?
+Which process is writing to disk and/or causes the disk to spin up?
+
+First of all use lsof to check what's going on. Does not help? ->
# echo 1 > /proc/sys/vm/block_dump
-Warning: you must disable syslogd before you do this, or you must
-make sure that kernel output is not logged.
+The command sets a sysctl to cause the kernel to log all disk
+writes. Please notice that there is a lot of data. So please
+disable syslogd/syslog-ng before you do this, or you must make
+sure that kernel output is not logged.
When you're done, disable block dump using:
# echo 0 > /proc/sys/vm/block_dump
Alternative:
laptop-mode-tools provides a tool named lm-profiler (laptop mode profiler)
which handles block_dump on its own.
+
+See: $KERNEL-SOURCE/Documentation/laptop-mode.txt
+
+Also take a look at event-viewer(8) which is part of grml-debugtools.

Install initrd via initramfs-tools for currently running kernel:
# xfs_admin -l /dev/sda1
reiserfs without vol_id:
-# debugreiserfs /dev/sda1 | grep UUID
+# debugreiserfs /dev/sda1 | grep -i label

+jfs without vol_id:

reiser4 without vol_id:
-# debugfs.reiser4 /dev/sda1 | grep uuid

Display stats about memory allocations performed by a program:
Usage example for 'ls':
* If you change the time (using 'date --set ...', ntpdate,...)
it is worth setting also the hardware clock to the correct time:
- # hwclock --hctosys [--utc]
+ # hwclock --systohc [--utc]
Remember to add the --utc -option if the hardware clock is set
to UTC!
