dracut-initqueue timeout

Dracut during initqueue is trying to understand what is your root device that he needs to mount and he can’t understand it… so you probably need to fix the cmdline in your boot.

1- Check if SDA* or Logical Group Name is missing or has been changed

2- Boot your Server into Rescue

3- use blkid command to locate/print block device attributes

# blkid
/dev/ram0: UUID="4a9ee2e6-a7fd-4c33-a95e-998482e1d9a7" TYPE="ext2"
/dev/sda1: PARTLABEL="primary" PARTUUID="96080286-cd99-4994-84f0-32633275666d"
/dev/sda2: LABEL="root" UUID="cccb8548-0f70-49c0-bf3c-abe9a0544d0c" TYPE="ext3" PARTLABEL="primary" PARTUUID="6bf115ff-b584-44ff-bdb1-ef9011a63ab0"
/dev/sda3: UUID="8910d5d3-77d7-4d40-b9f7-b12d025617ca" TYPE="swap" PARTLABEL="primary" PARTUUID="74bcd17b-f8c0-4c25-a428-287c7f9ab8b2"
/dev/sda4: UUID="agrUA9-zne0-UcYC-EdNi-wqb5-4Ch5-r6FRxz" TYPE="LVM2_member" PARTLABEL="primary" PARTUUID="fd1db930-34df-4d6f-91f6-616dd3ea750c"
/dev/mapper/vg00-database: LABEL="usr" UUID="1e78deeb-1173-4ca5-b9ee-a42ea7afeb56" TYPE="ext4"
/dev/mapper/vg00-var: LABEL="var" UUID="2cfb49db-3be3-4f05-b7d1-c6d2a60751cc" TYPE="ext4"
/dev/mapper/vg00-home: LABEL="home" UUID="3602b303-dd4f-4c74-99ad-1b24849382f1" TYPE="ext4"

The Issue here was, Volume Group “usr” has been changed to “database”

/dev/mapper/vg00-database: LABEL="usr" UUID="1e78deeb-1173-4ca5-b9ee-a42ea7afeb56" TYPE="ext4"

4- Mount your Hard Drive into /mnt Directory

# mount /dev/mapper/vg00-var var/
# mount /dev/mapper/vg00-home home/
# mount /dev/mapper/vg00-database usr/

5- cat fstab file

# cat /mnt/etc/fstab
/dev/sda2 / ext3 defaults,noatime 1 1
/dev/sda3 none swap sw
/dev/vg00/usr /usr ext4 defaults,noatime 0 2
/dev/vg00/database /database ext4 defaults,noatime 0 2
/dev/vg00/var /var ext4 defaults,usrquota,noatime 0 2
/dev/vg00/home /home ext4 defaults,usrquota,noatime 0 2
devpts /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /tmp tmpfs defaults 0 0

6- unmount all Drives

# umount -a

7- List Logical volume

# lvdisplay

8- Rename wrong volume group to the correct volume group

# lvrename /dev/vg00/database /dev/vg00/usr
  Renamed "database" to "usr" in volume group "vg00"

9- Correct the mount Directories in fstab file: we have commented /dev/vg00/database mount point

# cat /mnt/etc/fstab
/dev/sda2       /               ext3    defaults,noatime        1 1
/dev/sda3       none            swap    sw
/dev/vg00/usr     /usr          ext4    defaults,noatime        0 2
#/dev/vg00/database /database   ext4   defaults,noatime        0 2
/dev/vg00/var   /var            ext4    defaults,usrquota,noatime       0 2
/dev/vg00/home  /home           ext4    defaults,usrquota,noatime       0 2
devpts          /dev/pts        devpts  gid=5,mode=620  0 0
none            /proc           proc    defaults        0 0
none            /tmp    tmpfs   defaults        0 0

10- Reboot Server into Local mode again.

# reboot
