Hello

On my My Cloud 2TB dashboard, there is a critical notification named “Data volume failed to mount”.

The LED has turned red on the NAS.

I listed partitions by entering “df -H” :

WDMyCloud:/dev# df -HFilesystem      Size  Used Avail Use% Mounted onrootfs          2.1G  2.1G     0 100% //dev/root       2.1G  2.1G     0 100% /tmpfs            42M  3.7M   39M   9% /runtmpfs            42M   66k   42M   1% /run/locktmpfs            11M     0   11M   0% /devtmpfs           5.3M     0  5.3M   0% /run/shmtmpfs           105M  3.3M  102M   4% /tmp/dev/root       2.1G  2.1G     0 100% /var/log.hddramlog-tmpfs     21M  2.8M   19M  14% /var/log
 4 4828MB 2000GB 1996GB primary

And if i try to reset by entering :

/usr/local/sbin/factoryRestore.sh noreformat

 It gives me :

/usr/local/sbin/factoryRestore.sh: line 33: echo: write error: No space left on device

 How can I clean the rootfs folder?

Sorry for my english, i’m french

somthing doesn’t look right there, i will try to take a closer look tonight

in the meantime try the command below to look for large files

find / -type f -size +100M -exec ls -l {} ;
