similar to: raidz failure, trying to recover

From: Jean-Christian de Rivaz <jc at eclis.ch> I suspect that some instructions about how to use the diag/mbr was not updated when the source file was renamed to handoff.S. Here is a simple proposition to fix that.

I'm trying to destroy a zfs array which I recently created. It contains nothing of value. # zpool status pool: storage state: ONLINE status: One or more devices could not be used because the label is missing or invalid. Sufficient replicas exist for the pool to continue functioning in a degraded state. action: Replace the device using 'zpool replace'.

So, I've long known and it makes sense that when you're booted from a ZFS volume, you can't mess with the boot-loader. And, I know a few months ago I had a set of commands I would use when booted from a CD that would initialize the network and copy the "release/boot" from somewhere else so that I could install bootblocks and boot-loaders from more recent code. Sadly, I

Hi experts zpool import shows some weird config of an old zpool bash-3.00# zpool import pool: data1 id: 7539031628606861598 state: FAULTED status: One or more devices are missing from the system. action: The pool cannot be imported. Attach the missing devices and try again. see: http://www.sun.com/msg/ZFS-8000-3C config: data1 UNAVAIL insufficient replicas

G''day, all, So, I''ve decided to migrate my home server from Linux+swRAID+LVM to Solaris+ZFS, because it seems to hold much better promise for data integrity, which is my primary concern. However, naturally, I decided to do some benchmarks in the process, and I don''t understand why the results are what they are. I though I had a reasonable understanding of ZFS, but now

I have seen conflicting examples on how to create zpools using full disks. The zpool(1M) page uses "c0t0d0" but OpenSolaris Bible and others show "c0t0d0p0". E.g.: zpool create tank raidz c0t0d0 c0t1d0 c0t2d0 c0t3d0 c0t4d0 c0t5d0 zpool create tank raidz c0t0d0p0 c0t1d0p0 c0t2d0p0 c0t3d0p0 c0t4d0p0 c0t5d0p0 I have not been able to find any discussion on whether (or when) to

Hi, my system (solaris b77) was physically destroyed and i loosed data saved in a zpool mirror. The only thing left is a dettached vdev from the pool. I''m aware that uberblock is gone and that i can''t import the pool. But i still hope their is a way or a tool (like tct http://www.porcupine.org/forensics/) i can go too recover at least partially some data) thanks in advance for

1. I have a 4x18GB drive setup as RAIDZ. Now when thinking about it in terms of RAID5 I would expect to get (4-1)x18 worth of drive space, but DF -h shows 4x18. Is this a bug or do I not understand? 2. Once again thinking in RAID5 terms if I have 4X18GB and 12X9GB drives and I want to make a RAIDZ of all of them I would expect the 18GB to be treated at 9GB so the RAIDZ would be 16X9GB. Is

OK, I''ve been putting off this question for a while now, but it eating at me, so I can''t hold off any more. I have a nice 8 gig memory stick I''ve formated with the ZFS file system. Works great on all my Solaris PC''s, but refuses to work on my Sparc processor. So I''ve formated it on my Sparc machine (Blade 2500), works great there now, but not on

Hi all, Sorry for the newbie question, but I''ve looked at the docs and haven''t been able to find an answer for this. I''m working with a system where the pool has already been configured and want to determine what the configuration is. I had thought that''d be with zpool status -v <poolname>, but it doesn''t seem to agree with the

Hi all, IHACWHAC (I have a colleague who has a customer - hello, if you''re listening :-) who''s trying to build and test a scenario where he can salvage the data off the (internal ?) disks of a T2000 in case the sysboard and with it the on-board raid controller dies. If I understood correctly, he replaces the motherboard, does some magic to get the raid config back, but even

Hi, well, I was finally able to build syslinux-5.11-pre8 from git, but the system doesn't boot with the self-compiled version. All I see is: http://666kb.com/i/cfplluqpcy6owptq3.jpg Build log can be found in http://www.syslinux.org/archives/2013-July/020452.html After I installed the self-compiled syslinux version, I run this commands: # cd /boot/extlinux # rm -rf *.c32 # extlinux

Hello, We are experiencing a strange behaviour on an embedded system (i386 PC board). The structure of our disk is the following one : - A 2GB fat16 partition with DOS and syslinux - A 100GB Ext4 partition with Extlinux an several linux images to boot on ram - A swap partition The system boot on syslinux to choose among Dos and Linux boot using chain. When Linux is chosen, syslinux chains to

I have had some difficulty creating a bootable ESXi installation media on a USB disk in Windows(Kickstart scripts read by VMwares Weasel are not running properly), it works in Linux. The problem might have nothing to do with Syslinux, but I still want to ask a question regarding Syslinux to be sure there are variations as result of installing Syslinux to a USB drive in Windows vs Linux. In Linux

The vendor wanted to come in and replace an HDD in the 2nd X4500, as it was "constantly busy", and since our x4500 has always died miserably in the past when a HDD dies, they wanted to replace it before the HDD actually died. The usual was done, HDD replaced, resilvering started and ran for about 50 minutes. Then the system hung, same as always, all ZFS related commands would just
