3 - 4 when /usr is a vinum volume?
Hi! I'm having troubles updating a FreeBSD 3-stable system to current, since it has /usr as a vinum volume. I've just updated about a dozen machines without any problems, but none of them uses vinum. Following the instructions in UPDATING, when rebooting to single user mode, vinum wouldn't work since the kernel module was out of date - no surprise. So, I copied a fresh vinum.ko in there and tried again. This time, vinum loaded fine, but complained that it couldn't get the list from disk (or similiar). A 'vinum list' command would show nothing. So, I tried rebooting with the old 3-stable kernel. When makeing installworld running the 3-stable kernel, make first installed the make binary itself, and then could not do anything more, since the new libc was not in place, and the just installed make needed the new libc... odd? shall it really start by installing make? dunno how this happened? Anyway, what is a good strategy for upgrading a system where /usr is a vinum volume? Any tips, tricks or ideas (apart from moving /usr to a non-vinum volume and install onto that one).

I had fiddled with the settings for a specific purpose, and forgot to set them back. :-/ Read the loader page carefully and you should be able to boot 3.x kernels with 3.x modules and 4.0 modules with a 4.0 kernel without too much voodoo. Thanks for the tip. I'm not sure I read it close enough, for I set the module_path and it didn't help. Still, after installing all of the klds, I never really had to go back to the 3.x kernel, so it was ok anyway. The problem is of course that the UPDATING documentation lack info about installing the klds, and I didn't think about it. /Palle To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

Following the instructions in UPDATING, when rebooting to single user mode, vinum wouldn't work since the kernel module was out of date - no surprise. Hmm. After updating, you should have had new klds as well. But that's probably not your fault. Could you enter a PR about it, please? Yes. It's a documentation bug, as has been pointed out by Daniel C. Sobral. So, I copied a fresh vinum.ko in there and tried again. This time, vinum loaded fine, but complained that it couldn't get the list from disk (or similiar). How similar? That statement doesn't really help very much. Vinum produces error messages to help pinpoint problems. Unfortunately, I didn't write it down. I regret it. Here's briefly what happened: since 'start' didn't work, I tried to read the configurations off the disks one by one, which wasn't a very good idea, apparently, for since they weren't all started at once(?), some plexes were marked a faulty. I rebooted the kernel-3.x and started vinum with the old kld. It started and read all disks, but some were still marked faulty or flaky. I stopped and restarted the plexes/disks/subdisks quite a bit before got them all up again. It seems to me that vinum sometimes isn't quite logical about its decisions as to whether a disk/plex/sd is up or flaky. Is there a trick with the restarting sequence if a disk is marked flaky? I got the error 16(?) (device busy) a lot, and had to reboot again to get rid of them. After installing all klds and remaking the devices, I got the kernel-4.0 to read all the disks with the start command. 3-stable kernel, make first installed the make binary itself, and OK. Here's another documentation bug, imho. I missed moving the /etc/rc.conf.local away. make all depends on target upgrade_checks and it installs make if the test target fails. I think there should be a note to run make test before installworld. My make binary was blown away with no warning, and I was lucky to have another 3.x system left to fetch it from... It looks like you shot yourself in the foot. Yeah, that's one way to put it :) I'd have to find out what went wrong first. It looks as if it should have worked modulo the problems installing the klds. Yep. I'm preparing a pr for documentation bugs.

can't dump vinum volumes after upgrading
Hi! I'm having a strange problem after upgrading: There are no raw devices created for vinum volumes. This makes dump(8) puke. This is a 3.4 system: ls -laF /dev/vinum ... crwxr-xr-- 1 root wheel 91, 1 2 Jul 1999 rusr* drwxr-xr-x 2 root wheel 512 2 Jul 1999 rvol/ ... brwxr-xr-- 1 root wheel 25, 1 2 Jul 1999 usr* drwxr-xr-x 4 root wheel 512 2 Jul 1999 vol/ ... and here's a 4.0: crw-r- 1 root wheel 91, 0 21 Mar 13:40 usr drwxr-xr-x 11 root wheel 512 21 Mar 13:40 vol/ vinum makedev doesn't help. what gives? /Palle To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
Re: can't dump vinum volumes after upgrading
Hello again. I did some rtfm and src digging, it appears the listing I gave is correct; the raw devices are in the rvinum dircetory. Problem is, dump looks in vinum/r*. There seems that vinum introduces a bug here, since dump's rawname function replaces the last '/' in the device name with '/r'. In my 3.4 systems I have both rvinum and vinum/r* in my /dev directory. One solution is for vinum to create symlinks /dev/vinum/rplex - /dev/rvinum/plex, to help dump find the raw device from the fstab entry. That's what I'm doing manually now to get my filesystems dumped. This should probably be handled by vinum somehow? /Palle To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
Re: can't dump vinum volumes after upgrading
This fixes it for me.

Indeed there are. You list them below. There are no longer any block
devices.
This was a block device.
...
This is now a character device.
OK. Of course. Cool!
You don't describe what dump has to say. I know that they put in a
fix recently, but you don't say how old your system is.
The system is 4.0-STABLE, which is more or less 4.0-RELEASE right
now.
dump fails at the point were it is trying to convert the block
device listed in fstab to a raw device, by inserting a 'r' after
the last '/' in the pathname. This part of dump wasn't changed
since the initial import :)
in sbin/dump/main.c:546:
char *
rawname(cp)
char *cp;
{
static char rawbuf[MAXPATHLEN];
char *dp = strrchr(cp, '/');
if (dp == NULL)
return (NULL);
*dp = '\0';
(void)strncpy(rawbuf, cp, MAXPATHLEN - 1);
rawbuf[MAXPATHLEN-1] = '\0';
*dp = '/';
(void)strncat(rawbuf, "/r", MAXPATHLEN - 1 -
strlen(rawbuf));
(void)strncat(rawbuf, dp + 1, MAXPATHLEN - 1 -
strlen(rawbuf));
return (rawbuf);
}
So, here what dump says:
trumpet:vinum# dump 0af /dev/null /cluster1
DUMP: Date of this level 0 dump: Wed Mar 22 02:10:20 2000
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/vinum/rcluster1 (/cluster1) to /dev/null
DUMP: Cannot open /dev/vinum/rcluster1
which is rather expected.
My fstab has the line:
/dev/vinum/cluster1 /cluster1 ufs rw 2 2
Since you've enlighted me with the fact that there are only
character devices in vinum nowadays, my suggestion is putting a
symlink rfilesys-filesys in /dev/vinum for each filesystem, or
creating device nodes named rfilesys as well. This would make
dump(8) happy anyway.
Also, the manual pages (both vinum(4) vinum(8)) seem to be a bit
off here, since they mention both raw devices,
/dev/rvinum/rfilesys and /dev/vinum/rfilesys, none of which I
have (I do have /dev/rvinum/filesys, but they were probably made
under 3.4, right? Can I remove them?).
Oh, by the way, I love vinum. Thanks for all the hard work!
Cheers,
Palle

Remote access to HP Proliant hardware available to fix the problem with failing booting 9.0 on ciss(4), HP SmartArray P410i
Hi, When installing 9.0 RC1 on our HP servers, we of course wanted to use gpt intead of fdisk. However, it doesn't work. First I tried gptzfsboot, it failed with an error (see this thread: http://lists.freebsd.org/pipermail/freebsd-current/2011-August/026175.html) Second, I tried a standard gptboot, it just goes into a boot loop. Seriously, we have a couple of idle machines with ciss(4) and an iLO (for remote connections). If someone has the knowledge and time to try and fix the problems with ciss and gpt boot, we have the equipment for it. We tried with a standard vanilla zpool, no mirror or raid at all, on top of a ciss raid-5, and it failed with RC1. [trying RC2 now, but seems nothing is changed?]. Anyone up to the task of finding this culprit, we can let you into the machine remotely through the iLO. Please let me know.

Perhaps the BIOS is assuming it always gets the full thing even if we pass in a 1.1-sized structure. Just try putting a edd_params_v4 structure after the normal one. Yes, I'll try that.

netd in free(): warning: junk pointer, too low to make sense.
Hi! I'm experiencing some strange errors with one of our workstations. I recently moved all of our workstations to 3.0 current as of 1998-12-18. Does any of this make any sense to anyone: trumpet:~rlogin balalaika netd in free(): warning: junk pointer, too low to make sense. trumpet:~telnet balalaika Trying 1.2.3.4...

FreeBSD/i386 (balalaika.partitur.se) (ttyp2) login: username Ok... I get in... If I'm lucky. Sometimes not at all. Besides, it acts a little strange. For example, here's what newsyslog told me recently: newsyslog: preposterous process number: 77243 newsyslog: log not compressed because daemon not notified Restarting inetd fixes the problem with rlogin/telnet, but it is bound to come back within a day or so. My guess is that this started when we started using samba on the machine, for sharing some simple stuff to windows machines. The samba has probably not been recompiled since our elf transition (our server uses the same binaries, and serves them via nfs to the troubled machine), so there shouldn't be a problem. Anyway, I fetched the brand new 2.0 port of samba, but still have problems. I haven't modified the smb.conf, though. It seems at first that it is the inetd that has some kind of memory leak, but I really don't like that idea. Well... Any ideas appreciated.

panic: aha0 Invalid CCB or SG list
(Sorry for the crosspost, but I'd like to now if this is fixed in -current) Hi! I've seen three crashes in the last couple of weeks, with a server box that's been running stable as a rock for two years, at least. It has an adaptec 2940UW with six disks, and an adaptec 1542CP that's connected to a seagate travan tape driver. It's running STABLE-3.1 from Feb 19 1999, and since the last upgrade, I've seen three crashes, all related to dumping to tape. Since I got no info on what happened, I decided to sit down with the machine, run a backup sequence to tape, and wait for it to possibly crash. After 90 minutes, I was about to give up when suddenly, poof: panic: aha0 Invalid CCB or SG list. So, it's probably the 1540 driver (or hardware)? Can anybody shed some light on what to do? Is it software? That's my guess, since the machine never ONCE has crashed until the upgrade to 3.x. I had one crash when running current form beginning of January (soon after moving to 3.x), and now theese three in a week. The 1540 has been in the machine for about six months. Before starting the panicking backup, I spawned off a few logs: netstat -I de0 -w 5 and vmstat -p sa -p da -w 5 I'm not sure how to interpret them, but there's an excerpt at the end of this mail of the vmstat output (it stops in the middle of a row, when the crash occurred). The backups are made with amanda (see the ports collection), and uses gzip, hence the outbursts of cpu load. The netstat seems pretty uninteresting; quite normal. If there's anything I can do to help debug I'll do it, but device drivers are a little above my level of expertise. Thanks in advance! /Palle Here's a dmesg: Copyright (c) 1992-1999 FreeBSD Inc.

Re: panic: aha0 Invalid CCB or SG list
Hi Warner! Sorry to intrude, but I just want to check that I didn't miss any messages in this thread. Have you found anything that might be causing this problem? I think it's related to the 100% CPU utilization while writing full speed to both the ahc2940uw on pci and the 1542CP on isa. I realize this is not the easiest thing to debug; I had to sit and watch the screen for 90 minutes before it happened... Drop me a mail if you find anything.
