That was last year. In the mean time I've added an FTL to the driver, so the card behaves like a regular ssd. Well, mostly. > Is it possible to have logfs over the PCIe-SSD card? YeaaaNo! Not anymore. Could be lack of error correction in the current driver or could be bitrot. Logfs over loopback seems to work just fine, so if it is bitrot, it is limited to the mtd interface. > Pardon me for asking the following in this thread. > I have been trying to mount logfs and i face seg fault during unmount > .

Yes, ever since that machine died I have basically been the non-maintainer of logfs. In a different century I would have been hanged, drawn and quartered for it. Give me some time to test the mtd side and see what's up. Jörn -- Write programs that do one thing and do it well. Write programs to work together.
