Thread: partition has no UUID


i can't linux partition show uuid; doesn't seem have one.

blkid shows uuid of ntfs windows xp partition , linux swap partition (/dev/sda6), nothing linux partition (/dev/sda5).

doesn't show in /dev/disks/by-uuid either.

tried fix running gparted, does list uuid, same uuid tht used have before screwed (ran windows fixmbr trying boot windows, didn't work either), , added uuid symlink in /dev/disks/by-uuid*

ran update-grub2 , worked!!! grub.conf found , used uuid of partition... until rebooted.

it's missing again /dev/disks/by-uuid , doesn't output blkid either.

way can boot machine editing grub2 boot menu , replacing uuid entry /dev/sdx5, x depending on drives have plugged in @ moment.

know why isn't showing up, , how fix it? need written mbr or something?

have working machine, it's annoyance, i'd better understand how works.

bunch,

code:
sudo tune2fs /dev/sda6 -u "your current uuid" sudo update-grub

    Fyi for anyone working on this no uuid issue. I ran the XP recovery console commands, bootcfg /rebuild, fixboot and fixmbr while logged into the XP install and the commands executed on a different hard disk which had Linux installed. I booted the Linux install and got an error that ntldr or whatever was missing. I did a chroot grub re-install and found I was missing the UUID, so I’m guess the partition table was messed up. What I did to resolve this was I backed up the Linux partition using fsarchiver, formatted the disk, restored the partition, used tune2fs to restore the old UUID -which may not be necessary- and did the chroot grub install and update again.
    Be real, be sober.

hi, if developing platform independent software in linux using gtk+/gtkmm , you've managed cross compile windows, guide you. i'm posting because after researching topic myself, encountered many posts people have abandoned gtk+/gtkmm wxwidgets because of gtks ugly default appearance in windows/wine. gtk+ themeable in windows/wine gnome. have set correctly . . . here's how. guide gtkmm gtk+ similar. (1) firstly, download , install gtkmm windows using wine. (you have if have cross compiled app windows) https://live.gnome.org/gtkmm/mswindows (2) run these commands create proper directory structure.

hello! i'm trying setup software raid on server, fail @ first step: code: root@sandnabba:/root# mdadm -c /dev/md0 -c512 -l5 /dev/sdc1 /dev/sdd1 /dev/sde1 mdadm: no raid-devices specified. what doing wrong!? are sure -c equivalent --create? also, think need space after -c , -l options, value shouldn't command, or should have = between. @ man pages mdadm , double check spelling.
