Nobody showed any interest in looking at the :problems - in fact, the email wasn't even answered. : :As a consequence, FreeBSD lost out for being considered a candidate :at NASA/Ames for large mass storage. Shrug...It may or may not be :true that softupdates, per se, are stable. In my opinion, FFS as :offered by FreeBSD (and NetBSD) have not shown themselves to be :adequate to large (>500GB) filesystems. Sad to say, ext2 under :linux works better. Matt, I don't recall seeing anything from you in regards to large filesystems. Looking in the archives, I see one report on Jan 27th from you relating to softupdates, but you indicate that softupdates was not enabled on the volume in question, so it seems unlikely that it is related to softupdates specifically. There have been several reports of dirty-buffer panics which is of concern, but I haven't been able to reproduce the panic myself yet. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
