The synocli-disk package provides some disk related tools to advanced Linux users. Most of the tools must be run as privileged user (root) to work or to get access to related resources.

Tool Description License

ntfs-3g / ntfsprogs Third generation read/write NTFS driver and NTFS utilities. GPLv2
TestDisk TestDisk is powerful free data recovery software. GPLv2+
ncdu Ncdu is a disk usage analyzer with an ncurses interface, designed to find space hogs where you don't have an entire graphical setup available. MIT
davfs2 Mount a WebDAV resource as a regular file system. GPLv3
lsscsi The lsscsi command lists information about SCSI devices in Linux. GPLv2
dar DAR is a shell command that backs up from a single file to a whole filesystem, taking care of hard links, Extended Attributes, sparse files, MacOS's file forks, any inode type, etc. GPLv3

When you call smartctl you will get the older version of Synology DSM; to call smartctl of this package, call smartctl7 (or /usr/local/bin/smartctl or /var/packages/synocli-disk/target/sbin/smartctl). To update the device database call update-smart-drivedb. GPLv2

davfs2 - Mount WebDAV Shares

Before you can mount webdav folders with davfs2, you have to execute once the following commands see issue #4466:

Create links in /usr/sbin: 

sudo ln -s /usr/local/bin/mount.davfs /usr/sbin/mount.davfs
sudo ln -s /usr/local/bin/umount.davfs /usr/sbin/umount.davfs

Create the user davfs2:davfs2: 

sudo synouser --add davfs2 "" "" 0 "" 0
sudo synogroup --add davfs2 davfs2
