$ مستخدم عادي# بصلاحية root (أو مع sudo)

1. 1After fdisk

   #partprobe /dev/vdb
   #lsblk /dev/vdb

   New partitions now have device files.

2. 2Show what it found

   #partprobe -s /dev/vdb
   /dev/vdb: gpt partitions 1 2 3

   Quick check.

3. 3All disks

   #partprobe

   Probes every disk.

4. 4When it fails

   #partprobe /dev/vda
   Error: Partition(s) 2 on /dev/vda have been written, but we have been unable to inform the kernel...

   The disk is busy (system disk). A reboot may be needed, or use partx.

5. 5Alternative: partx

   #partx -u /dev/vdb

   Updates only the changed partitions.

6. 6Wait for udev to create the devices

   #partprobe /dev/vdb; udevadm settle

   In scripts, before mkfs.

7. 7Dry run

   #partprobe -d -s /dev/vdb

   Test without changing anything.

8. 8After growing a VM disk

   #echo 1 > /sys/class/block/vdb/device/rescan; partprobe /dev/vdb

   The kernel learns the new disk size (for SCSI/virtio with rescan support).

9. 9Check the result with the kernel view

   $cat /proc/partitions

   The kernel's list of partitions.

10. 10In an automated disk setup

    #parted -s /dev/vdb mklabel gpt mkpart data xfs 1MiB 100% && partprobe /dev/vdb && mkfs.xfs /dev/vdb1

    Each step only when the step before worked.
