# trim2unmap
A workaround to let SSD TRIM work on some SAS RAID cards.
## Warning
No warranty provided, use this at your own risk
## Build
### Dependencies
- [BUSE](https://github.com/ReimuNotMoe/BUSE)
### Compile
Nearly all my projects use CMake. It's very simple:
mkdir build
cd build
cmake ..
make -j `nproc`
## How to use
Load the `nbd` kernel module first.
```
modprobe nbd
```
Syntax:
```
trim2unmap
```
e.g.
```
trim2unmap /dev/sdd /dev/nbd10
```
Then you can mount your virtual device like mounting the physical device as usual
```
mount /dev/nbd10 /mnt
```
