No problem. The kernel code should still handle the corruption better, but I know where it's happening. > As a side note, this might be a good forum for the newbie question, We kind of dropped the "forum".

I'm a bit biased, but jfs handles large files quite well. I don't think it's widely used in network servers, since I just recently found out that quotas had been broken for quite some time. If you're not using quotas, I'm not aware of any other issues, though. > Are there > choices that are obviously better? I haven't played with MythTV myself. I thought about it, but directv gave me a good deal on a dvr. :-) I think I've seen recommendations for both xfs and jfs. I don't know if one is clearly better than the other. > I appreciate your help! > Thanks, > Will Constable > > -----Original Message----- > From: Dave Kleikamp [mailto:[EMAIL PROTECTED] > Sent: Wednesday, December 13, 2006 12:24 PM > To: Will Constable > Subject: RE: [Jfs-discussion] Help with Samba+JFS > > On Wed, 2006-12-13 at 11:23 -0500, Will Constable wrote: > > Thanks for your response!
