I have two linux partitions on my laptop (one ubuntu and one garuda). Ubuntu was giving me problems so I installed Garuda to check it out. The Garuda partition filled up so I used KDE partition manager to shrink the ubuntu partition so I could expand the Garuda.
Then, Ubuntu wouldn't mount and would not boot as it said the fs was wrong size. I ran fsck on the partition and hit yes to pretty much everything. This included force rewriting blocks it said it couldn't reach and removing inodes, etc. Probably a mistake in hindsight.
Now, I got a external hard drive and cloned the Ubuntu partition using "sudo dd if=/dev/nvme0n1p5 of=/dev/sda1 conv=noerror,sync". The external hard drive mounted without problem but it does not have /home/ folder, only folders such as /etc/.
I don't think there's many files I cant get back from a git repo, but it would be nice to have access to the /home folder so I can grab everything, remove the ubuntu partition, and resize garuda.
Thanks in advance!
I figured it out. I kind of followed https://unix.stackexchange.com/questions/129322/file-missing-after-fsck but
I copied the partition to an external drive using dd. Then mounted the external drive (which just worked even though I could not mount the original ubuntu partition). Then I went into the lost+found folder on the partition and used "find" to search for a file I know I had in my home folder and it found that file. I am not able to access all my documents etc.

I'm trying to run my static web app using Windows Subsystem for Linux (2), but I can't figure out where on my computer I should store the git repository to be able to run it decently quickly. I have tried storing it on under /mnt/c/{workfolder}, but it takes several minutes to start up (using npm run start), and I have to rerun to see any changes. This is useless when I'm trying to work...
I have also tried to store it in /mnt/wsl/{workfolder}, and in that case it starts up quickly and I can see my changes without rerunning the app. However, it seems to disappears when I restart my computer.
Where should I store the git repository to be able to run the app quickly and see changes without rerunning? I'm assuming there's something I'm not understanding, help me get this it you know.
You'll want it somewhere on the ext4 partition of the WSL distribution. Typically, the best place is going to be under your WSL /home/<username> folder.
I would recommend:
mkdir ~/src
# or
mkdir ~/projects
# or something similar
Then create subdirectories for each project in that directory.
Why the others don't work:
/mnt/c is the Windows C: drive. That drive is mounted into WSL2 using the 9P network file system, and yes, it's (a) slow, and (b) does not support inotify, so apps cannot register for notifications of changes to files.
/mnt/wsl is a tmpfs mount. It's really there for holding things that need to be shared between all running WSL instances. The auto-generated resolv.conf that you see there is one of those things. You can also use it for copying a file from one WSL distribution to another -- Simply copy the file to /mnt/wsl, start another WSL distribution, and copy or move the file out.
But yes, all tmpfs mounts are ephemeral and will terminate when the last WSL2 distribution/instance terminates.
By default, BlueZ stores its persistent data in /var/lib/bluetooth. This includes controller settings and information about paired devices. However, I'm working in a system where the /var directory is unreliable, so I wonder if there is any way I can change this directory?
I have seen examples where it can be changed during installation, with the "--localstatedir" flag, but I'm looking for a solution that doesn't require reinstallation.
Without reinstalling its not possible. Path is configured at compile time so recompilation and installation is required. You can replace STORAGEDIR macro with string which is read from main.conf to different path at runtime. After modifying these changes you can restart bluetoothd every time you change path then it works.
I'm running Ubuntu and have a remote CentOS system which stores (and has access to) various files and network locations. I have SSH access to the CentOS machine and want to be able to work locally on Ubuntu.
I'm trying to mirror a remote directory structure. The remote directory is structured:
/my_data/user/*
And I want to replicate this structure locally (a lot of scripts rely on absolute paths).
However, for reasons of speed, I want a certain subfolder, for example:
/my_data/user/sourcelibs/
To be stored locally on disk. I know the sourcelibs subfolder doesn't change much (but the rest might). So I can comfortably rsync it:
mkdir -p /my_data/user/sourcelibs/
rsync -r remote_user#remote_host:/my_data/user/sourcelibs/ /my_data/user/sourcelibs/
My question is, if I use sshfs to mount /my_data/user:
sudo sshfs -o allow_other,default_permissions, remote_user#remote_host:/my_data/user /my_data/user
Will it overwrite my existing files? Is there a way to have sshfs mount but exclude certain subfolders?
Yes, sshfs will overwrite existing files. I have almost the same use case and just tested this myself. BTW, you'll need to add -o nonempty to your sshfs command since the destination dir /my_data/user already exists.
What I found to work is make a copy of the remote directory excluding the large sub dirs. IDK if keeping 2 copies in sync on the remote machine is feasible for your use case? But if you'll mostly be updating on your local machine and rarely making changes remotely, that could work.
I am having the most frustrating issue with VQmod. I moved my OpenCart store from a Godaddy VPS to Rackspace's Cloud Sites. The move went fine and everything works properly except the VQmod's on the admin panel. None of them load. No errors in the log files, no admin cache files in the cache dir, no php errors.
Things I have tried:
Cleared all cache Changed admin folder to 755
reinstalled VQmod tried both manually and using the installer with fresh index.php files
Removed all XML files and tried to load only one at a time
Cursed loudly at my computer repeatedly.
Please Help! OC version 1.5.6 VQmod 2.5.1
For those that want the solution to this, the issue was that the config.php files were both using relative paths instead of the full paths for OpenCart's various directories. They should always be full paths, or resolved with realpath() in the config.php files themselves
My case was a bit different. I checked the permissions, paths, all the regular stuff that comes to mind first. I even walked step by step through the manual installation guide.
The Opencart copy in question is shared across several environments using git. Long story short, the mods.cache and checked.cache were not added to .gitignore right away, and when I finally did that, I emptied both of them just to make sure Opencart will write new content based on my current environment. Turns out, since mods.cache was empty, Opencart believed there are no mods available.
Solution: delete both vqmod/mods.cache and vqmod/checked.cache.
Update: here are some similar issues:
https://github.com/vqmod/vqmod/issues/32
https://github.com/vqmod/vqmod/issues/3
The vqmod/vqmod/wiki/Troubleshooting guide, as of now, does not make it obvious the files should've been deleted, neither does the vqmod/vqmod/wiki/Installing-vQmod-on-OpenCart, and there doesn't seem to be any way to contirbute. vQmod fails silently, without producing any notifications, warnings, or simply detecting the issue and rebuilding the cache files. I've spent few hours trying to figure out what's wrong.
Is there a way to direct the install of redcar to a user defined location other than a user home directory?
I have a jruby install on a USB drive, E:\jruby-1.6.2. Redcar installs the gems to the E:\jruby sub directory but then installs the user files to ~/ on c:.
Is there a way to direct it to e:\fakehome. I want to keep all installation files on my USB drive.
I do not have a Redcar-specific solution, but here is a general solution that may work for you.
PROBLEM:
The user has an application that installs application data files to a fixed location, but the user wants the files in a different location (such as a removable drive or a standardized app data directory).
SOLUTION:
Use a Junction Point or Symlink to simulate the presence of the pre-configured directory.
STEPS:
install the application normally
locate the pre-configured directory that you wish to have relocated (e.g. c:\users\foouser\appdata\fooapp)
create an empty directory with the same name in your alternate desired location (e.g., e:\myusbdrive\appdata\fooapp)
terminate the application you just installed if it is still running
move all of the files out of the pre-configured directory and put them in the desired directory
delete the toplevel pre-configured directory
create a junction that points to the toplevel pre-configured directory you just deleted from the alternate desired location
restart the application and use it normally, making sure that it still behaves normally.
If all goes well you should be finished.
Here i a link to a junction creator (for older versions of Windows (TM))

This response from Matthew Scharley directly answers how this can be done for redcar.
For the moment it is hard coded. Thankfully it is easy to change:
