ureadhead prevent the system from booting after fsck during 180 seconds

[Id2ndR]

Binary package hint: ureadahead

Steps to reproduce :
- Send sys keys : ALT+SYS+B during a boot
- fsck will be perfom during the reboot during few seconds
=> show that the percent change very slowly and there is no disk activity. In my case, it go from 0% to 70% normaly, and then from 70 to 90-91% very very slowly with no disk activity. Then it changed the number of drive to scan from 1 to 3. And finally the boot process resume.

Look at attached bootchart.

In fact this is not 180 seconds but 225 seconds (timout of 180 added to the sleep of 45 seconds). You can show it in the bootchart by this operation : 252 (begining of ureadhead) = 27 (end of fsck) + 180 + 45.

Hi, same problem here. There is also problem with canceling the check disk. When i press the "C" key, checking doesn't stop and still continue.

[Id2ndR (id2ndr)]

I get the trouble again on an other computer. This time it wasn't 180+45 seconds but more, so I check in logs files why.
In fact there was a trouble on checking two partitions so I think I can explain the delay with combination of sums of 180 and 45.

I also found (in this computer), that the trouble itself is not due to ureadead directly but a missing command (fsck.ntfs) on my system and ureadhead doesn't manage that.

See attached /var/log/boot.log and corresponding bootchart.

[Id2ndR (id2ndr)]

In my previous case, the bug with fsck.ntfs is https://bugs.launchpad.net/bugs/441242 and I fix the trouble by disabling the check as explain in https://bugs.launchpad.net/ubuntu/+source/partman-basicfilesystems/+bug/441242/comments/6

I'll report again when I'll get the trouble on the computer from which I create the bug report.

@all:
Please attach your /var/log/boot.log when the trouble occurs.

This massive delay actually sounds more like Bug 571707 ...

I'm marking this as a duplicate of bug 571707 that seems to be the same one. If it's not, I am unmarking it later.
