Re: computer boot (some times) in emergency mode.

[Angelo Moreschini <mrangelo.fedora@xxxxxxxxx>]

Hi 

I had serious problems.

Because I didn't  check immediately the hard disk with the bad sector,  the time of booting stretched at every subsequent  opening; and, at last, I was not able anymore  to start Fedora  ..

So I had to make the restore of my installation, using a clone that I took before, by Clonezilla.. (luckily).

Now I  want only to check why a HD, 'Western Digital with only a few months of life, has gone faulty ..

I know there are programs, made by the manufacturers of HD, that allow you to make these types of control

Hi Chris,

I would be more inclined to to think about a electrical problem, since the
only rep-plugging of the connectors of the HD solves the problem ..
In any case I think the control of the HD  is appropriate, so I would ask
you in detail how to do this operation:

This is what I get with the command blkid (the output concern only the
partition where is the OS Fedora):

/dev/sdc1: UUID="4b1e5e09-306b-4c17-8c2f-653b32e1b956" TYPE="ext4"
PARTUUID="0008635c-01"
/dev/sdc2: UUID="Vtbdeq-eq6H-sbMY-Mpme-UyFk-jx77-I5Z20K" TYPE="LVM2_member"
PARTUUID="0008635c-02"
/dev/mapper/fedora-root: UUID="2d224b16-d37f-4eee-820a-dfcd5929e05e"
TYPE="ext4"
/dev/mapper/fedora-swap: UUID="54d55595-8c35-4e84-8566-89d8b6f340e8"
TYPE="swap"


so I should do :
e2fsck -f /dev/sdc1
and after
e2fsck -f /dev/sdc2

This is enough ?

After I did I'll ask you more..

I am sorry about the message... I would include a photo of the output but
the administrator of the mail list didn't do it because the message had a
size too much big..

thank you
Angelo

I had some strange issues on a computer and it turned out to be the power supply.  A known issue with the 5V rail on the supply not regulating properly.  Especially under load.  I have a stack of DVD's of backups of data that are almost coasters due to this issue.

If you can, setup up lm_sensors and monitor your system voltages.

Also check the drive for issues as it could be failing.
