I have seen many folk who have signatures stating that the machine has been running for something like 400 days.
Whilst I applaud this type of reliability, I am wondering about the actual fs as the machine isn't rebooted so that fsck can check the partitions.
I am perhaps paranoid about keeping the fs in tip top shape but it is the basis that we all rely on.
YES! You are! :-P X'-)
so my question is this: Can a system that has such uptime have its all its fs checked and not be rebooted?
No need to check them... this is linux, stability is the word here ;-)
Could a system Linux boot floppy specific to the system be inserted, mounted, and then be told to unmount the running systems partitions listed in the fstab(except the floppy, and fsck them and then re-mount them, without losing the uptime figure?
Hah! That floppy has no chance. If it is a boot floppy, it can not boot - unless you reboot. If it is a program, it has no other access than the running system has.
The only posibility is umount a partition, one that is not used at the time, then fsck it. That means that you will never be able to check "/". In fact, you can not even check "/home" without login everybody off first.
The only theoretical posibility would be, when using a raid 1, mirror, and puting it in single disk mode (if possible in linux, I don't know). One of the halfs would be active, the other could be checked. The problem, and a big one, would be when reactivating the raid: files will have changed during that time: how can you resync both drives...? a nightmare.
I know a machine that can do that, kind of, but not a linux machine, and not a PC, and with a really huge price tag. Since I am unemployed, I'll have to give that machine a skip Carlos. :)
Tnx though. I guess I just gotta start trusting the Linux OS and STOP comparing to that other GUI OS.
