Then when I get the detach event for /dev/da0 device I know what to u(n)mount … but when I only have /dev/fuse device its just not possible.
When I mount such filesystem by my daemon (like sysutils/automount) I keep track of what device have been mounted to which directory in the /var/run/automount.state file. % mount -t fusefs /dev/fuse on /mnt/ntfs (fusefs) When you mount – for example – the /dev/da0 device as NTFS (with ntfs-3g) or exFAT (with mount.exfat) there is no visible difference in mount(8) output. I was also not able to cover FUSE mounts. % glabel status | grep ada0p1 gpt/efiboot0 N/A ada0p1
As not all FAT filesystems have label I have chosen the GPT label. We have both /dev/gpt/efiboot0 label and FAT label is named EFISYS. One of them is ‘double’ label for FAT filesystems. Things that does not have simple solution are described below.
Great example why “less is more.” % wc scripts/lsblk.sh.OLD It has similar SLOC but its now smaller by a quarter … while doing more and with better accuracy. In other words its 2.0 version.ġ file changed, 494 insertions(+), 505 deletions(-)Īfter several productive hours new incarnation of lsblk.sh is now available. … at least this is what git(1) tries to tell me after commit message.
#NTFS 3G FOR FREEBSD UPDATE#
UPDATE 2 – Code Reorganization and 75% Rewrite I think I will create dedicated man page when lsblk.sh tool will grow in size and options to comparable with the Linux lsblk(8) equivalent. IMHO writing man page for such simple utility is needless. Just added some usage information that can be displayed by specifying one of these as argument: If I got time which other original Linux lsblk(8) subcommand/option/argument is worth adding to the lsblk.sh script? 🙂
#NTFS 3G FOR FREEBSD INSTALL#
If you would like to install it in your system just type the command below: # fetch -o /usr/local/bin/lsblk While lsblk.sh is not the fastest script on Earth (because of all the needed parsing) it does its job quite well. # lsblk.shĭa0p1 0:15a 200M efi efiboot0 ĭa0p3 0:15c 2.0G freebsd-swap swap0 ĭa1p1 0:16a 200M efi efiboot1 ĭa1p3 0:16c 2.0G freebsd-swap swap1 īelow you will find other examples from other systems I have tested lsblk.sh on. % lsblk.shĪda0p1 0:64 200M efi efiboot0 īelow you will find an example lsblk.sh output from server with two system SSD drives ( da0/ da1) and two HDD data drives ( da2/ da3). Here is example output of lsblk.sh command from my single disk laptop. The lsblk.sh is generally small and simple shell script which tales less then 400 SLOC. I actually ‘open-sourced’ or should I say shared that project/idea in 2016 in this thread lsblk(8) Command for FreeBSD on FreeBSD Forums but lack of time really slowed that ‘side project’ development pace.
As I have long and pleasing experience with writing shell scripts such as sysutils/beadm or sysutils/automount I though that writing lsblk.sh may be a good idea. While lsblk(8) has many interesting features like -perms/ -scsi/ -inverse modes I focused to provide only the basic feature – to list the system block devices and their contents. What if you would like to display a summary of all system drives contents? This is where lsblk.sh comes handy. They provide needed information in acceptable manner but only on systems with small amount of disks. Please note that because of WordPress limitations I need to change all > 40 1953525088 ada0 GPT (932G) Below you will find output of these commands from my single disk laptop. You can also use gpart(8) command to list partitions. What FreeBSD offers in this department? The camcontrol(8) and geom(8) commands are available. It has some problems like listing a disk that is entirely used under ZFS pool on which lsblk(8) displays two partitions instead of information about ZFS just being there – but we all know how much in some circles the CDDL licensed ZFS is unloved in that GPL world.Įxample lsblk(8) output from Linux system: $ lsblk An example of such tool is lsblk(8) that does one thing and does it quite well – lists block devices and their contents. … but sometimes – which rarely happens – Linux has some very useful tool that is not available on FreeBSD. When I have to work on Linux systems I usually miss many nice FreeBSD tools such as these for example to name the few:
