** Description changed:
PROBLEM
When a disk check is performed, the progress stalls somewhere around 70%
and will then take a very long time finishing the remaining percent (10
minutes or more).
- POSSIBLE WORKAOUNDS
+ TEST CASE:
- 1. Simply waiting several minutes for mountall to realize that the disk
- check is complete. You should not see this problem on subsequent boots,
- until the next disk check is necessary.
+ (sudo aptitude install bootchart)
+ sudo touch /forcefsck && sudo reboot
- 2. Removing "quiet" and "splash" from the kernel boot line
+ POSSIBLE WORKAROUNDS
- 3. When the progress has stalled, switch away from the splash screen using
the left arrowkey (presumably any arrowkey works).
- This could speed up the boot process to ~1 minute instead of ~10+.
+ 1. Removing "quiet" and "splash" from the kernel boot line
+
+ 2. When the progress has stalled, switch away from the splash screen
+ using the left arrowkey (presumably any arrowkey works).
+
+ * Both these approaches speeds up the boot process to ~1 minute instead.
+
+ OBSERVATIONS
+
+ The fsck message "(...) non-contiguous (...)" Which I assume indicates
+ the end of the fsck, is printed in the Virtual Terminal ("outside"
+ plymouth) at around 70% + ~10-20 seconds.
+
+ Disk activity is null from this point on (presumed end of fsck above).
+
+ Bootchart crashes if trying to catch the whole boot at once with
+ plymouth (at least for my 1h boot).
+
+ This problem seems to occur in both plymouthd and mountall,
semi-simultaneously:
+ If you are in the plymouth screen, plymouthd is the cpu-gobbler, if you
switch away from it using the arrow keys, mountall instead takes over the
cpu-eating.
+
+
+ #####
ORIGINAL REPORT
Binary package hint: mountall
On my system when fsck runs at boot plymouth % completion count goes up
quickly (<10 seconds) up to about 80% and then slows down considerably:
the complete fsck of my 125GB HD, 30% full takes more than 5 minutes.
While this goes on the text VTs are all completely blank: just a
blinking cursor.
An fsck from a recovery disk completes in ~10 seconds so it doesn't look
like "fsck just being slow".
This slowdown was *not* happening on 2010-04-14 with the PPA described
by this comment:
https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/554737/comments/25
The fix in the PPA is now in the mainline lucid but somewhere in between
then and today (2010-04-29) something introduced this slowdown.
