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/sdcfsck from util-linux 2.37.2e2fsck 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/sdcGPT 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 formatin memory. THIS OPERATION IS POTENTIALLY DESTRUCTIVE! Exit bytyping 'q' if you don't want to convert your MBR partitionsto GPT format!***************************************************************  Warning! Secondary partition table overlaps the last partition by33 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): zAbout to wipe out GPT on /dev/sdc. Proceed? (Y/N): yGPT data structures destroyed! You may now partition the disk using fdisk orother utilities.Blank out MBR? (Y/N): y

之后再看就正常了

$ sudo gdisk /dev/sdcGPT 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): nPartition number (1-128, default 1): First sector (34-2813066894, default = 2048) or {+-}size{KMGTP}: Last sector (2048-2813066894, default = 2813066894) or {+-}size{KMGTP}: Current type is 8300 (Linux filesystem)Hex code or GUID (L to show codes, Enter = 8300): Hex code or GUID (L to show codes, Enter = 8300): Changed type of partition to 'Linux filesystem'Command (? for help): w Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTINGPARTITIONS!! Do you want to proceed? (Y/N): yOK; 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/sdcGPT 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/sdcfsck from util-linux 2.37.2e2fsck 1.46.5 (30-Dec-2021)ext2fs_open2: Bad magic number in super-blockfsck.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/sdc1fsck from util-linux 2.37.2e2fsck 1.46.5 (30-Dec-2021)1T4B: clean, 11/87908352 files, 5800552/351633105 blocks

如果需要检查硬盘, 用 gdisk /dev/sdc, 然后在里面用 v 命令

根据网上搜索到的结果, 大部分原因为: 供电问题, 硬盘硬件问题, 以及文件格式错误. 参考 https://forums.gentoo.org/viewtopic-t-815278.html
将整块SSD重新格式化为ext4后, 未再报错.
