X-BeenThere: freebsd-stable@freebsd.org List-Id: Production branch of FreeBSD source code List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 22 May 2005 13:46:25 -0000 I have 6 servers in place right now, with the 6th being a brand new Intel 1U box, using a 3Ware 9500 controller to do RAID5 for 3xSATA drives ... yesterday, for the first time, I've started to get a sort of file system corruption that I've never seen before ... basically, it looks like the directory entries are getting corrupted, but the files themselves are fine ... Basically, I have a jail, with /usr in the jail being a unionfs from a template ... so: mount_union -b /template/usr /jail/usr in the template, there is a directory /usr/local/cyrus/bin, for instance ... the binaries under /usr/local/cyrus/bin are literally disappearing, as if someone were entring that directory and doing a 'rm' of those files ... I have a serial console attached to this server, and there are no errors being reported by the operating system ... tw_cli is showing that drives and unit are both functioning properly ... so I can find no reasons for the apparent "corruption" ... I just brought the server down to single user mode, and umounted everything so that I could do an fsck on the file system itself, and *its* checking as being clean ... its still running though, so there may be something at the end ... When I first noticed this, yesterday, the server had been running 11 days, and nothing in /var/log/messages to indicate a problem ... today, after <24hrs, its done it again, and again, no errors being generated anywhere to indicate a problem ... All the other 5 servers are running SCSI ... but unless there is a bug in the 9500 driver, I can't see it being hardware related ... I've kinda always expected something like this might happen with unionfs as a result of the server crashing, but not when its running fine ... I don't know what else to add to this, unfortunately, since neither the hardware, or the operating system, seem to want to give anything up :( The OS is from April 11th, so is relatively recent ... Any suggestions/ideas on what else to look at would be much appreciated ... Thank you ... ---- Marc G.
