kernel: swap_pager: indefinite wait buffer - on 5.3-RELEASE-p5
Hello All, I have a pretty stable FreeBSD 5.3-p5 production server which worked just fine - until today. I host over 100+ web sites on it (Apache + PHP4 + MySQL), email, ftp, etc. There was a time when it was up for over 6 months without a reboot. So it is stable. But today I had a strange problem with this server. I could ping it, but nothing else worked. I had to reboot it by plugging the power. After it came back, this is what I've found in the log file (and nothing else).

works just fine since the reboot. Not even fsck was needed (file system didn't get dirty by plugging the power???)... I've never seen this error message before. This could be an indication of what? A dying IDE hard drive??? I happen to have an identical hard drive around here, unused. If I hook it up as a slave (IDE) drive, is there a way I can mirror the dying drive to the spare one (with all partitions, etc, intact)? Any help/comments would be appreciated. Please CC me, as I am not a subscriber of this list. Thanks!!! Zoltan

Try to mirror the disk with dd (if=/dev/ad0 of=/dev/ad1 bs=1m) You should really think about getting a RAID controller, i can recommend you a 2 channel 3ware controller (less than 100$) Kind regards Steven -- ++ message delivered by gizm0.org <http://gizm0.org/> ++ free webmail - imap, pop3, ssl secured Zoltan Frombach wrote:> Hello All, > > I have a pretty stable FreeBSD 5.3-p5 production server which worked > just fine - until today.

The error message indicates that there was an I/O error
accessing the swap area on your disk. Usually that's an
indication for a hardware failure, e.g. a dying disk.

If they're really identical (i.e. the same size and same
geometry), then you can use dd(1) for duplication, like
this:
# dd if=/dev/ad0 of=/dev/ad1 bs=64k conv=noerror,sync
The "noerror,sync" part is important so the dd command will
not stop when it hits any bad spots on the source drive and
instead will fill the blocks with zeroes on the destination
drive. Since it's only the swap partition, you shouldn't
lose any data.
However, one disadvantage of dd is that it copies the drive
on block level, which means that it will also copy empty
blocks which aren't used at all. Neither does it make
sense to copy the swap partition.
If the filesystems on that drive don't contain much data,
it might be mor efficient to copy the data on filesystem
level. To do that, copy just the boot sector and disklabel
(using dd(1) to copy the first 64k or something should be
sufficient), then newfs the filesystems, mount them and
copy the contents with an appropriate tool. I recommend
"cpdup" from the port collection, because it's fast and
easy to use, but cpio should work as well (and it's in the
base of pretty much every UNIX system).
Performing newfs + filesystem copy also has the advantage
that you're starting with fresh, unfragmented filesystems,
and it gives you the opportunity to finetune the parameters
if necessary, such as the inode density (newfs -i).

In that case you should set the "Reply-To" header in your
mail appropriately.

Steve, Thank you for your quick response!> Try to mirror the disk with dd (if=/dev/ad0 of=/dev/ad1 bs=1m)I assume I have to do this in single user mode. Right?> You should really think about getting a RAID controller, i can recommend > you a 2 channel 3ware controller (less than 100$)Would you please email me the product name and model number?

Mike,
Thank you so much for the information you have provided. I installed
smartmontools from ports, what a great tool!
However, I see 0 (zero) Reallocated_Sector_Ct ... So the hard drive seems to
be okay? I attach the full output below. Is there someone knowledgeable
about HD Smart information, who can possible tell me if this drive looks
like if it is failing?
