Thank Bob, it works
Then, It can reproduce the issue
under fdisk, I delete 2 partitions (6 and 7) and create 2 new ones
(with different size).
Then I get:
/dev/sdd1 4096 26617855 26613760 12.7G 7 HPFS/NTFS/exFAT
/dev/sdd2 26619705 38909429 12289725 5.9G 7 HPFS/NTFS/exFAT
/dev/sdd3 38909430 49142834 10233405 4.9G 7 HPFS/NTFS/exFAT
/dev/sdd4 49142835 976768064 927625230 442.3G 5 Extended
/dev/sdd5 49142898 98301734 49158837 23.5G 82 Linux swap / Solaris
/dev/sdd6 190466703 251915264 61448562 29.3G 83 Linux
/dev/sdd7 251915328 309267314 57351987 27.4G 83 Linux
/dev/sdd8 309270528 461461503 152190976 72.6G 83 Linux
/dev/sdd9 98304000 99327999 1024000 500M 83 Linux
/dev/sdd10 99330048 190466639 91136592 43.5G 83 Linux
Partition table entries are not in disk order.
Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Re-reading the partition table failed.: Device or resource busy
The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).
Then, if I want to fix the partition order with fdisk expert f
it mess up every thing again!
What do I need to run?
Thank.
