So we accidentally caused our server to go down without a clean shutdown and now
df is reporting wrong stats for the external usb (exfat).
root@srv1:/backup/usbdisk# df -h Filesystem Size Used Avail Use% Mounted on /dev/sdb2 3.6T 2.8T 646G 82% / ... /dev/sde1 7.3T 241M 7.3T 1% /backup/usbdisk
root@srv1:/backup/usbdisk# du -sh 2.6T .
exfatfsck /dev/sde1 says:
exfatfsck 1.1.0 WARN: volume was not unmounted cleanly. Checking file system on /dev/sde1. File system version 1.0 Sector size 512 bytes Cluster size 128 KB Volume size 7452 GB Used space 241 MB Available space 7452 GB ERROR: cluster 0x3f of file 'assets' is not allocated. ERROR: cluster 0x40 of file 'mysql' is not allocated. ERROR: cluster 0x41 of file 'public_assets' is not allocated. Totally 3 directories and 0 files. File system checking finished. ERRORS FOUND: 3.
so how do we fix this?
