I have several TBs of very valuable personal data in a zpool which I can not access due to data corruption. The pool was originally set up back in 2009 or so on a FreeBSD 7.2 system running inside a VMWare virtual machine on top of a Ubuntu 8.04…

I am going to chop the FreeBSD automounter into little pieces and boil them in oil

Why is Linux more popular than BSD?

Some would argue that BSD/Unix has always been more reliable and stable than Linux (not me, of course, don't hurt me!). Why does Linux always seem to beat BSD? Is it the romance of the Linux story? I don't intend to offend anyone, please don't take…

FreeBSD: How to know real file size on zfs with compression on?

I'm using zfs on my FreeBSD 9.0 x64 and pretty happy with it, but I find it hard to count directory real, not compressed, size. Surely I can walk over the directory and count every file size with ls, but I'd expect some extra key for du for that…

FreeBSD Jails or Docker instances

What are the main differences between jails on FreeBSD and Docker on Linux? Is one considerably more secure or more performant than the other? Jails are way older than Docker instances so the code itself could be considered more secure. But Jails…
