磁盘问题和解决: fsck,gdisk,fdisk等
错误: Resize inode not valid对于gpt分区的硬盘一般fsck只能检查分区, 不能用于检查整个硬盘, 但是如果对硬盘设备运行时遇到这样的错误
$ sudo fsck -n /dev/sdc
fsck from util-linux 2.37.2
e2fsck 1.46.5 (30-Dec-2021)
GW1.5T was not cleanly unmounted, check forced.
Resize inode not valid.Recreate? no用 gdisk检查一下分区表, 可能会提示下面的信息
$ sudo gdisk /dev/sdc
GPT fdisk (gdisk) version 1.0.8
Partition table scan:
MBR: MBR only
BSD: not present
APM: not present
GPT: not present
***************************************************************
Found invalid GPT and valid MBR; converting MBR to GPT format
in memory. THIS OPERATION IS POTENTIALLY DESTRUCTIVE! Exit by
typing 'q' if you don't want to convert your MBR partitions
to GPT format!
***************************************************************
Warning! Secondary partition table overlaps the last partition by
33 blocks!
You will need to delete this partition or resize it in another utility.对于这种情况, 需要清空GPT和MBR, 命令 x -> z -> y * 2
Command (? for help): x
Expert command (? for help): z
About to wipe out GPT on /dev/sdc. Proceed? (Y/N): y
GPT data structures destroyed! You may now partition the disk using fdisk or
other utilities.
Blank out MBR? (Y/N): y之后再看就正常了
$ sudo gdisk /dev/sdc
GPT fdisk (gdisk) version 1.0.8
Partition table scan:
MBR: not present
BSD: not present
APM: not present
GPT: not present用gdisk分区
Command (? for help): n

Command (? for help): w
Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!
Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/sdc.
The operation has completed successfully.分区之后, 会显示GPT信息
$ sudo gdisk /dev/sdc
GPT fdisk (gdisk) version 1.0.8
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.错误: Bad magic number in super-block
如果用fsck直接检查GPT分区的硬盘时就会报这个错误
$ sudo fsck -n /dev/sdc
fsck from util-linux 2.37.2
e2fsck 1.46.5 (30-Dec-2021)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdc需要指定文件系统对应的分区进行检查
$ sudo fsck -n /dev/sdc1
fsck from util-linux 2.37.2
e2fsck 1.46.5 (30-Dec-2021)

将整块SSD重新格式化为ext4后, 未再报错.
