Can you provide verbose boot messages of your system from the beginning
up to the problem? Especially, all related to the ATA.



Attached.

It's set up as AHCI in the bios.

What is strange is that it has now started working again. I can't make 
any sense of it. The machine boots up fine.  It was definitely hanging 
at the ata probes though, just after the ZFS messages are output.

So, it's a ZRAID2 pool with a ufs/gmirror root partition split over 5

What I did was to update the userland, and then reboot. I didn't
upgrade
the

What happens is that the kernel hangs booting just after displaying a

single
user with acpi switched off. When I do that I can manually start
zfs, and
mount all the partitions. However, one of the disks is missing

that next.

The machine is running a gigabyte motherboard (domestic gamer P35

although it might be a DS4 variant). I've got 5 of the 6 sata ports
wired
to a 5 unit SATA hot swap bay (5 drives vertially mounted into 3
5-1/4"
bays
kind of thing).

Now, because of the gmirror I can boot the system on any disk, or
combination of plugged in disks. I should be able to succeed with the
kernel probe up to the attempt to mount the root filesystem
irrespective
of
any zfs pool, etc. And, indeed, this has been working fine for
about two
years.

But, now it hangs in the same place no matter what disk I boot on
(I've
tried every bay).

But, without ACPI enabled it does appear to boot ok... what's going on
here?
Is it possible that the machine has developed a hardware fault?

Ok, finally, if I boot with ACPI disabled then one of the disks is
missing.
If I unplug it I get a disconnect message from the ata device, and a
reconnect and reinit attempt when I plug it back in, but no device
appears
on the bus. Usually I can do a 'atacontrol detach sata4; sleep 1;
atacontrol
attach sata4' and the device reappears. This happens on the other
buses,
but
not on the last one. It's not the disk, because if I swap it into
another
bay, it comes up and appears on the bus. On the other hand it doesn't
appear
to be that controller or slow in the drive bay because if I unplug all
the
over disks the system will boot that disk and get as far as the
hang
hmm.

Is this a consequence of disabling the ACPI?

Does anyone have a clue what might be going on?

2009-05-22 Thread Larry Rosenman 

I saw really strange stuff with one bad SATA cable on my 6 drive ZFS array.
It would work most of the time, but
the scrub would either cough up CRC's or hang.

I wound up replacing the disk *AND* the cable, and it's been fine since. 

This is on a SuperMicro chassis with Intel chips.

YMMV

This appears to have gone away now. I unplugged the bay that was causing 
the trouble, and the system booted just fine on the remaining 4 drives. 
Then I plugged the bay back in (live) and did an atacontrol 
detach/attach on that bus (I wonder why I always have to do that). The

Strange, so it looks like a cable might have got a little loose or 
something. I wonder why that would have hung the kernel probe though.

bay, it comes up and appears on the bus. On the other hand it doesn't

Is this a consequence of disabling the ACPI?

Does anyone have a clue what might be going on?

Hmm, I've had a bit of a miserable afternoon trying to fight my RELENG_7

So, it's a ZRAID2 pool with a ufs/gmirror root partition split over 5 disks
(gmirror on 500Mb partition on each of five disks, and zraid2 over the rest
of each drive).

What I did was to update the userland, and then reboot. I didn't upgrade the
kernel (but I've subsequently done that and have the same problem).

What happens is that the kernel hangs booting just after displaying a LABEL
message or ZFS pool/spool message. I _can_ get it to boot if I boot single
user with acpi switched off. When I do that I can manually start zfs, and
mount all the partitions. However, one of the disks is missing more on
that next.

The machine is running a gigabyte motherboard (domestic gamer P35 board,
similar to this
http://www.gigabyte.com.tw/Products/Motherboard/Products_Overview.aspx?ProductID=2533,
although it might be a DS4 variant).  I've got 5 of the 6 sata ports wired
to a 5 unit SATA hot swap bay (5 drives vertially mounted into 3 5-1/4" bays
kind of thing).

Now, because of the gmirror I can boot the system on any disk, or
combination of plugged in disks. I should be able to succeed with the
kernel probe up to the attempt to mount the root filesystem irrespective of
any zfs pool, etc. And, indeed, this has been working fine for about two
years.

But, now it hangs in the same place no matter what disk I boot on (I've
tried every bay).

But, without ACPI enabled it does appear to boot ok... what's going on here?
Is it possible that the machine has developed a hardware fault?

Ok, finally, if I boot with ACPI disabled then one of the disks is missing.
If I unplug it I get a disconnect message from the ata device, and a
reconnect and reinit attempt when I plug it back in, but no device appears
on the bus. Usually I can do a 'atacontrol detach sata4; sleep 1; atacontrol
attach sata4' and the device reappears. This happens on the other buses, but
not on the last one. It's not the disk, because if I swap it into another
bay, it comes up and appears on the bus. On the other hand it doesn't appear
to be that controller or slow in the drive bay because if I unplug all the

FWIW, I love sysutils/ezjail.  It uses nullfs to mount many jails on top of 
the same read-only base system, and provides a way ("ezjail-admin update -i") 
to upgrade that base system with installworld.

ZFS hanging at kernel boot now, but didn't before... (Re: ZFS MFC heads up)

2009-05-21 Thread Joe Karthauser 
Hmm, I've had a bit of a miserable afternoon trying to fight my RELENG_7 
server, which now doesn't boot. :(.


So, it's a ZRAID2 pool with a ufs/gmirror root partition split over 5 
disks (gmirror on 500Mb partition on each of five disks, and zraid2 over 
the rest of each drive).


What I did was to update the userland, and then reboot. I didn't upgrade 
the kernel (but I've subsequently done that and have the same problem).


What happens is that the kernel hangs booting just after displaying a 
LABEL message or ZFS pool/spool message. I _can_ get it to boot if I 
boot single user with acpi switched off. When I do that I can manually 
start zfs, and mount all the partitions. However, one of the disks is 
missing more on that next.


The machine is running a gigabyte motherboard (domestic gamer P35 board, 
similar to this 
http://www.gigabyte.com.tw/Products/Motherboard/Products_Overview.aspx?ProductID=2533, 
although it might be a DS4 variant).  I've got 5 of the 6 sata ports 
wired to a 5 unit SATA hot swap bay (5 drives vertially mounted into 3 
5-1/4" bays kind of thing).


Now, because of the gmirror I can boot the system on any disk, or 
combination of plugged in disks. I should be able to succeed with the
kernel probe up to the attempt to mount the root filesystem irrespective 
of any zfs pool, etc. And, indeed, this has been working fine for about 
two years.


But, now it hangs in the same place no matter what disk I boot on (I've 
tried every bay).


But, without ACPI enabled it does appear to boot ok... what's going on 
here? Is it possible that the machine has developed a hardware fault?


Ok, finally, if I boot with ACPI disabled then one of the disks is 
missing. If I unplug it I get a disconnect message from the ata device, 
and a reconnect and reinit attempt when I plug it back in, but no device 
appears on the bus. Usually I can do a 'atacontrol detach sata4; sleep 
1; atacontrol attach sata4' and the device reappears. This happens on 
the other buses, but not on the last one. It's not the disk, because if 
I swap it into another bay, it comes up and appears on the bus. On the 
other hand it doesn't appear to be that controller or slow in the drive 
bay because if I unplug all the over disks the system will boot that 
disk and get as far as the hang hmm.


Is this a consequence of disabling the ACPI?

Does anyone have a clue what might be going on?

We might want to update the zfs(1) man page in the examples for the

just

a little unnerving at first to have the snapshots be missing after
the MFC.

Do 'zpool get all ', it might give you a hint as to why :-)

FYI, I just did an upgrade of my RELENG_7 machine with the new ZFS  
merged in, and it seems to have gone mostly trouble-free.  I noticed  
one weirdness that could be confusion on my part - I'm no longer  
seeing snapshots when I do 'zfs list'.  There's a UI change in the zfs  
command, and to see snapshots, you have to explicitly ask for them:


zfs list -t snapshot

scared me there for a moment..

Thanks for all the great work on ZFS in FreeBSD to everyone involved.   
I look forward to really beating on this now in RELENG_7.


Any pointers to running multiple jails with ZFS?  I was looking for  
something like a union-mount capability for ZFS.  I don't necessarily  
need a jail to run divergent /bin, /usr/local, etc. just the  
isolation.  Making a clone doesn't exactly do the same thing..

IIRC, that's what happens if ZFS kernel and userland aren't in sync.

You'll either have to install the new kernel and userland
together (not supported, but I do it all the time), or install
the userland from a non-ZFS file system.

I can't help, but thanks for the bug report as it prompted me
to upgarde both kernel and world at the same time. Which works
fine after reboot. If I were you I would reboot the old
kerenl and just installworld/meregmaster so you ahhve the whole
system in sync.

I think this is not a zfs issue, but it does trigger the problem:
on a zfs mounted system via nfs, from linux, an ls .zfs 
used to panic the server, now it just doesn't work :-).
(http://lists.freebsd.org/pipermail/freebsd-fs/2008-October/005217.html)

so is this being worked on?

btw, i will be trying the new version over the weekend.

Revision 185029 - (view) (annotate) - [select for diffs]
Modified Mon Nov 17 20:49:29 2008 UTC (6 months ago) by pjd
File length: 38244 byte(s)
Diff to previous 177698

Update ZFS from version 6 to 13 and bring some FreeBSD-specific changes.

This bring huge amount of changes, I'll enumerate only user-visible changes:

- Delegated Administration

Allows regular users to perform ZFS operations, like file system
creation, snapshot creation, etc.

- L2ARC

Level 2 cache for ZFS - allows to use additional disks for cache.
Huge performance improvements mostly for random read of mostly
static content.

- slog

Allow to use additional disks for ZFS Intent Log to speed up
operations like fsync(2).

- vfs.zfs.super_owner

Allows regular users to perform privileged operations on files stored
on ZFS file systems owned by him. Very careful with this one.

- chflags(2)

Not all the flags are supported. This still needs work.

- ZFSBoot

Support to boot off of ZFS pool. Not finished, AFAIK.

Submitted by:   dfr

- Snapshot properties

- New failure modes

Before if write requested failed, system paniced. Now one
can select from one of three failure modes:
- panic - panic on write error
- wait - wait for disk to reappear
- continue - serve read requests if possible, block write requests

- Refquota, refreservation properties

Just quota and reservation properties, but don't count space consumed
by children file systems, clones and snapshots.

- Sparse volumes

ZVOLs that don't reserve space in the pool.

- External attributes

Compatible with extattr(2).

- NFSv4-ACLs

Not sure about the status, might not be complete yet.

Submitted by:   trasz

- Creation-time properties

- Regression tests for zpool(8) command.

Hi,
Thanks for working on ZFS!   Is there a summary of the new 
features somewhere ?
