 |
|
I have had my linux box on for a week, and today I rebooted, and got this message when the system was shutting down:
| Code: | Enter root password for maintance..."
|
I did, and only got to this bash prompt. When I booted gentoo again, I have 7 Gb more free disk space...how come? |

Usually you get the "Enter root password for maintenance" message if something went wrong with fsck when checking your partitions on boot. I can't say exactly what you did, but you probably inadvertantly wiped 7GB from your disks in maintenance mode. If everything else seems to be working, and you're not missing any important files you created yourself, I wouldn't worry about it. But you need to be very careful when you enter maintenance mode.
If fsck failed I'd seriously look into why it might have failed. You might be looking at an imminent drive failure. Have you installed smartmontools?

I don't think the free space is really there at all. There might be a problem with either your filesystem, your drive, or both. 
Having 7GB extra free space sounds too good to be true. And in most cases, it is. |

Assuming you have SMART capable drives (most current ATA and SCSI hard drives do), you can use that capability to monitor the health of your drives. This Linux Journal article gives a good introduction to using SMART:
Monitoring Hard Disks with SMART
If you have any Serial ATA drives, SMART only supports them if you use the "standard" drivers/ide driver, and even then only if you have one of a specific set of SATA controllers. I say "standard" because most SATA drives are driven by the libata driver, which is part of the SCSI subset, so it's actually non-standard to be using the drivers/ide driver. SMART functionality should be added to the libata driver "real soon now(TM)." There already is an unofficial patch, but I'm afraid to use it. (-:

Maybe you had a lot of log files which are now gone. I once had the problem that someone tried to break into my router and that created almost 4 GB in log files and other files like mail....... .

No, the fsck (filesystem check) simply checks your filesystem to see if it's "integrity" is ok. The exact process varies for different filesystems, it sounds like something is corrupted or longer readable, most likely your hard disk is dieing. How long have you had it for? Run fsck manually (do it from LiveCD, doing it while having it mounted can damage it
