Synology Nas: Run Fsck To Check and Repair a Linux File System

To run the fsck utility to check and repair a Linux file system on a Synology NAS, you need to have access to the command line interface of the device. You can do this by using the ssh command to log into the NAS from a remote computer, or by using the built-in Terminal or Console feature in the Synology DiskStation Manager (DSM) interface.

Here’s the basic procedure for running fsck on a Synology NAS:

1. Log into the NAS using ssh or the Terminal/Console feature in DSM.

2. Identify the file system that you want to check and repair. This is typically done by mounting the file system and then using the df command to view a list of mounted file systems and their associated device files.

3. Unmount the file system that you want to check and repair by using the umount command, followed by the device file of the file system. For example, if the device file is /dev/sda1, you would use the following command:

4. Run the fsck command, followed by the device file of the file system. For example, to run fsck on /dev/sda1, you would use the following command:

fsck will run and perform a check of the file system, fixing any errors that it finds. Note that running fsck on a mounted file system is not recommended and can result in data loss or corruption, so it’s important to unmount the file system before running the fsck command.

After running fsck, you should remount the file system by using the mount command.
