To find the inode size of an ext2 or ext3 filesystem on a Linux machine, you can use the tune2fs command. This command allows you to view and modify the filesystem parameters of an ext2 or ext3 filesystem.
To view the inode size of an ext2 or ext3 filesystem, you can use the following command:
tune2fs -l /dev/<device> | grep "Inode size"
Replace /dev/<device> with the device name of the filesystem you want to check. For example, if the filesystem is on the /dev/sda1 device, you would use the following command:
tune2fs -l /dev/sda1 | grep "Inode size"
This will print a line like Inode size: 256, which indicates the inode size of the filesystem in bytes.
Note that the tune2fs command requires superuser privileges to run, so you may need to use sudo to run the command.
You can also use the dumpe2fs command to view the inode size of an ext2 or ext3 filesystem. This command allows you to dump the filesystem parameters of an ext2 or ext3 filesystem to the standard output.
To view the inode size of an ext2 or ext3 filesystem using dumpe2fs, you can use the following command:
dumpe2fs /dev/<device> | grep "Inode size"
Replace /dev/<device> with the device name of the filesystem you want to check. This will print a line like Inode size: 256, which indicates the inode size of the filesystem in bytes.
Again, note that the dumpe2fs command requires superuser privileges to run, so you may need to use sudo to run the command.
