Re: Help, please, understanding AHCI error on amd64
It seems that after reading the backblaze and google papers about drive reliability that there is no statistically obvious difference. It's too close to call. Both papers end with hedges and further questions. Even if enterprise drives are more reliable it isn't by more than a single percent and it isn't consistent enough to matter either.

Unless your installation is very specific and there is something precious beside /home and /etc/, just do a dump, install, restore. Also, are there any /etc/fstab options recommended for SSDs? None which you wouldn't use for a classical disk as well.

Re: Is Ext2 stable enough for normal use?
Tekk, The compatibility between linux ext and unix ufs (aka ffs in 4.4BSDs) is terrible. Both the linux kernel developers think ufs is a quagmire and the BSD kernel folks don't use extX so they don't really know if it works. Google Unix File System and hit the wikipedia article which explains how this mess was evolved into being. I have a perverted solution, use fat32. It's failures are very well understood.

Your subject asks about the stability of the ext2 support in OpenBSD, but your message says you have an ext3 partition you want to access. ext2 and ext3 are not the same thing -- ext3 is a journaled variant of ext2 that OpenBSD does not support. See http://www.openbsd.org/faq/faq9.html Don't do it. My understanding is read/write access is considerably more risky than read-only access. If you just need to read that /home under OpenBSD it's much less complicated and less risky as you can just mount /home read-only and be done with it (even if it's still ext3). At minimum, if you insist on read-write, you should get rid of the journal thus converting ext3 back to ext2. It's a Really Bad Idea to mount ext3 as ext2 read-write unless you are extra careful to shut down cleanly every time and even then it's dubious. It *might* be less risky if you format that /home as FFS and access it using the Linux kernel's UFS/FFS module. Or, you could simply keep separate /home for GNU/Linux and OpenBSD, which to me is perhaps the cleanest solution. (I tend to compile a lot of stuff and install it to $HOME/bin when I don't want it cluttering up /usr/local/bin which is something I will admit a lot of users probably don't do.) ext2 is a side line for OpenBSD, not used as much and therefore not as well-tested as the ffs code. The same is true for Linux, exchanging ext2 and ffs. I'd be very disinclined to trust a file-system I cared about to code that hasn't been heavily beaten upon. I learned this the hard way when I encountered a bug in FreeBSD's ext2 support that killed the system and damaged the file-system. This was some years ago, but as I recall, I had to resort to using Linux's fsck to put things back together. The original post implies that he wants write access to the file-system from both OpenBSD and Linux, so mounting read-only probably doesn't serve his purpose. It he converts his ext3 file-system to ext2, then he can mount read-write with OpenBSD, assuming the OpenBSD ext2 code supports 256-byte inodes, and run the risk of discovering a bug in the OpenBSD ext2 code. And he loses the protection of the journal when running Linux. I think your suggestion of separate /home file-systems makes the most sense. -- Shawn K. Quinn skqu...@rushpost.com
Re: NFS/Samba Alternative
Hello Byron, Firstly, are they windows 7 pro or enterprise? Most people don't know any difference but one that I have found is that Enterprise included the Microsoft NFS client along with their other Unix interoperability tools. Of course almost no one buys enterprise because it much more expensive. If you have Windows 7 Pro then this is what I have found, even though it's not much to work with. It depends on whether in transit security is important to you. If you can get away without it ftp is your best choice. This is a tough situation that I have tried to find clever solutions to but they are few and far between. Simply sharing files between computers is a nightmare for normal people because in simple situations like yours there isn't really a simple answer. Email and USB sticks are popular not because they're efficient, but because they work without tedious setup. If you are a domain admin then you could also install something like WinSCP and just configure SSH to be available on the box. I've even seen it work where you get the portable exe of a program and you can run it without installing it to a domain connected computer. Putty for example does this.
