Move Docker from File Based Storage to Dedicated Device

Step 1: Backup your docker images, individually

docker save imagename > backup_name.tar

Step 2: Stop docker service (service docker stop)

Step 3: Delete existing docker directory (rm -rf /var/lib/docker/*)

Step 4: Make new docker directory (mkdir -p /var/lib/docker/devicemapper/devicemapper)

Step 5: Create symbolic link to point to that device (ln -s /dev/sdb /var/lib/docker/devicemapper/devicemapper/data)

Step 6: Start docker and load your images (docker load < backup_name.tar)

Vmware Linux Guest Add a New Hard Disk Without Rebooting Guest


Step 1: Add disk in vmware settings (scsi, sata whatever you like)

Step 2: Tell Linux guest OS to detect this. If you just reboot the guest, it will detect automatically. If you don’t want to reboot, issue following commands

echo "- - -" > /sys/class/scsi_host/host#/scan
fdisk -l
tail -f /var/log/message

Step 3. Format new disk.

# fdisk /dev/sdb
# mkfs.ext3 /dev/sdb3

Step 4: Create a Mount Point And Update /etc/fstab

# mkdir /disk3
Open /etc/fstab file, enter:
# vi /etc/fstab
Append as follows:

/dev/sdc3               /disk3           ext3    defaults        1 2

for recover this, various options, below worked for me.

Create an exact copy of the existing table, partitioned if existing is partitioned.

replace the corrupt partition with old files, both MYD and MYI.

issue a “select * from newtable”

it will fix the table, now, transfer it to destination table.
