Re: e2fsck after hard shutdown
All of the disk repair tools are in the Fedora initramfs. This includes e2fsck, btrfs (check), and xfs_repair. It is possible to run it before root mounts by using rd.break=pre-mount as a mount option. --- Chris Murphy -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Re: e2fsck after hard shutdown
Ralf, do you mean that I could unmount my filesystems from inside the root window and proceed with e2fsck? tnx 2015-09-05 7:59 GMT+02:00 Ralf Corsepius : > On 09/05/2015 07:31 AM, antonio montagnani wrote: > > do you mean that I could run e2fsck from inside the root shell? >> > Yes. > > I >> guessed that filesystems were already mounted and e2fsck doesn't work on >> mounted filesystems I have to study. :-) >> > > Depends, depends on what actually happened/gone wrong. > > In most such cases, the filesystems are mounted read-only or not mounted > at all. > > Ralf > > > > -- > users mailing list > users@lists.fedoraproject.org > To unsubscribe or change subscription options: > https://admin.fedoraproject.org/mailman/listinfo/users > Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct > Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines > Have a question?

Normally fsck is run during boot, before filesystems are mounted read/write. You should only be dropped to the emergency shell if errors are found in filesystem, in which case you will be asked if and how those errors should be fixed. Advanced filesystems like btrfs and ZFS have checksums and other reliability measures that will help the filesystem driver automatically repair errors. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
