Re: [zfs-discuss] cannot replace c10t0d0 with c10t0d0: device is too small

2011-03-05 Thread Roy Sigurd Karlsbakk
 You cannot. That's why I suggested two years ago that they chop off 1%
 from the end of the disk at install time to equalize drive sizes. That
 way you you wouldn't run into this problem trying to replace disks
 from a different vendor or different batch. The response was that Sun
 makes sure all drives are exactly the same size (although I do recall
 someone on this forum having this issue with Sun OEM disks as well).

We had a disk crash some months back on a Sun pizzabox - disks were mirrored 
(linux software raid), so no problem, except the new drive was a bit smaller 
than the original. This was a replacement part from Sun^WOracle... Since the 
machine was a compute node, I ended up reinstalling it instead of waiting for 
another replacement.

Vennlige hilsener / Best regards

[zfs-discuss] cannot replace c10t0d0 with c10t0d0: device is too small

2011-03-04 Thread Robert Hartzell
In 2007 I bought 6 WD1600JS 160GB sata disks and used 4 to create a raidz 
storage pool and then shelved the other two for spares. One of the disks failed 
last night so I shut down the server and replaced it with a spare. When I tried 
to zpool replace the disk I get:

zpool replace tank c10t0d0 
cannot replace c10t0d0 with c10t0d0: device is too small

The 4 original disk partition tables look like this:

Current partition table (original):
Total disk sectors available: 312560317 + 16384 (reserved sectors)

Part  TagFlag First Sector Size Last Sector
  0usrwm34  149.04GB  312560350
  1 unassignedwm 0   0   0
  2 unassignedwm 0   0   0
  3 unassignedwm 0   0   0
  4 unassignedwm 0   0   0
  5 unassignedwm 0   0   0
  6 unassignedwm 0   0   0
  8   reservedwm 3125603518.00MB  312576734

Spare disk partition table looks like this:

Current partition table (original):
Total disk sectors available: 312483549 + 16384 (reserved sectors)

Part  TagFlag First Sector Size Last Sector
  0usrwm34  149.00GB  312483582

  6 unassignedwm 0   0   0
  8   reservedwm 3124835838.00MB  312499966
 
So it seems that two of the disks are slightly different models and are about 
40mb smaller then the original disks. 

I know I can just add a larger disk but I would rather user the hardware I have 
if possible.
1) Is there anyway to replace the failed disk with one of the spares?
2) Can I recreate the zpool using 3 of the original disks and one of the 
slightly smaller spares? Will zpool/zfs adjust its size to the smaller disk?
3) If #2 is possible would I still be able to use the last still shelved disk 
as a spare?

If #2 is possible I would probably recreate the zpool as raidz2 instead of the 
current raidz1.

Any info/comments would be greatly appreciated.

You cannot.  That's why I suggested two years ago that they chop off 1% from
the end of the disk at install time to equalize drive sizes.  That way you
you wouldn't run into this problem trying to replace disks from a different
vendor or different batch.  The response was that Sun makes sure all drives
are exactly the same size (although I do recall someone on this forum having
this issue with Sun OEM disks as well).  It's ridiculous they don't take
into account the slight differences in drive sizes from vendor to vendor.
 Forcing you to single-source your disks is a bad habit to get into IMO.

Well that sucks... So I guess the only option is to replace the disk with a 
larger one? Or are you saying thats not possible either?
I can upgrade to larger disks but then there is no guarantee that I can even 
buy 4 identical disks off the shelf at any one time.

Thanks for the info

2011-03-04 Thread Cindy Swearingen

Hi Robert,

We integrated some fixes that allowed you to replace disks of equivalent
sizes, but 40 MB is probably beyond that window.

Yes, you can do #2 below and the pool size will be adjusted down to the
smaller size. Before you do this, I would check the sizes of both
spares.

If both spares are equivalent smaller sizes, you could use those to
build the replacement pool with the larger disks and then put the extra
larger disks on the shelf.

Thanks,

Cindy

 Hi Robert,

 We integrated some fixes that allowed you to replace disks of equivalent

In former times, similar problems applied to partitioned disks with UFS 
and we at that time did check the market for the lowest disk size in a disk 
class and sold out disks with partitions that have been limited to the lowest 
size in order to be able to easily replace customer disks.

One comment: The IDEMA LBA01 spec size of a 160GB device is
312,581,808 sectors.

Instead of those WD models, where neither the old nor new drives
follow the IDEMA recommendation, consider buying a drive that reports
that many sectors.  Almost all models these days should be following
the IDEMA recommendations due to all the troubles people have had.

shelved disk as a spare?


If #2 is possible I would probably recreate the zpool as raidz2 
instead of the current raidz1.


Any info/comments would be greatly appreciated.

 In 2007 I bought 6 WD1600JS 160GB sata disks and used 4 to create a raidz

 When I tried to zpool replace the disk I get:
 
 zpool replace tank c10t0d0
 cannot replace c10t0d0 with c10t0d0: device is too small
 
 The 4 original disk partition tables look like this:
 
 Current partition table (original):
 Total disk sectors available: 312560317 + 16384 (reserved sectors)
 
 Part  TagFlag First Sector Size Last Sector
 0usrwm34  149.04GB  312560350
 1 unassignedwm 0   0   0
 2 unassignedwm 0   0   0
 3 unassignedwm 0   0   0
 4 unassignedwm 0   0   0
 5 unassignedwm 0   0   0

 So it seems that two of the disks are slightly different models and are 
 about 40mb smaller then the original disks.
 
 
 One comment: The IDEMA LBA01 spec size of a 160GB device is
 312,581,808 sectors.
 
 Instead of those WD models, where neither the old nor new drives
 follow the IDEMA recommendation, consider buying a drive that reports
 that many sectors.  Almost all models these days should be following
 the IDEMA recommendations due to all the troubles people have had.

Thats encouraging, if I have to I would rather buy one new disk then 4.

Get one that's a bit larger. It won't cost you a fortune. If the reseller is 
nice, you may even return the old one..

Vennlige hilsener / Best regards

 The response was that Sun makes sure all drives
 are exactly the same size (although I do recall someone on this forum
having
 this issue with Sun OEM disks as well).  

That was me.  Sun branded Intel SSD being reported 0.01Gb smaller.  But
after bashing my brains out for a few days, we discovered there was some
operation I could perform on the HBA which solved the problem.  I forget
exactly what it was - something like a factory installed disk label or
something, which I overwrote in order to gain that 0.01G on the new drive.

For this reason, I have made a habit of slicing drives, and leaving the last
1G unused.  It's kind of a hassle, but as Cindy mentions, the problem should
be solved in current releases.
