Long story short, my cat jumped on my server at my house crashing two drives at the same time. It was a 7 drive raidz (next time ill do raidz2). The server crashed complaining about a drive failure, so i rebooted into single user mode not realizing that two drives failed. I put in a new 500g replacement and had zfs start a replace operation which failed at about 2% because there was two broken

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.

Hi, > The ISO will boot successfully (when chainloaded from grub) on 2 and > 3, but not on 5 and 6. Did you try with a boot loader other than GRUB ? Afaik, the MBRs of newly bought USB sticks often contain code which hops on the MBR code of the partition that is marked by the boot flag. At least one could exclude that your problem is in a GRUB peculiarity. Have a nice day :) Thomas

Is there a way to find the holes in sparse files, other than assuming contiguous blocks of zeroes are holes? Thanks, Sean

Is it the isohdppx or isohdpfx (or both) that is relevant? Meanwhile I have a hacked isohdppx.bin that prints: G if GPT M if MBR <nothing> if no partition info E if EBIOS C if not EBIOS

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 a computer that dual boots between Windows and CentOS. Each has it's own hard drive. I suddenly have a problem with Windows, and may need to reinstall. I need it for applications like After Effects, Premiere, and other things that I am currently in the middle of a project with. It seems the system has become usnstable, it's preventing me from continuing to work, and I

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

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

What is the maximum speed for download from a samba share? I have a 100 kbit/s Internet The maximum speed for a download from my  webserver with samba is about 25.000 kbit/s The bottleneck is the samba access.  Without samba  I can download with 100 kbit/s So the question? is it possible to get more speed or is this the maximum speed with samba? I tried a lot of hints for samba tuning but

Hi guys, I have Xen 3.0.3 installed with yum on Centos 5.1. I''am facing an issue trying to resize the disk image of a centos 4.5 VM. The VM disk size is 50Go and i need to add 150Go. I tried two methods so far : -------------1st method----------------------- dd if=/dev/zero of=<image file> bs=1M conv=notrunc count=1 seek=2500 * losetup /dev/loop0 <image file> * e2fsck -f

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, I have a custom linux system that runs off a FAT32 usb flash disk. I use syslinux to make it bootable and load the kernel. I'm trying to boot now from a SSD SATA disk (500GB) but it's not working and I can't figure out why. BIOS show that no bootable disk were found. What I already tried (linux fdisk): 1- Creating a new DOS partition table on the SSD, a FAT32 (type b), and

Dear Mr Anvin, we use SYSLINUX for our industrial embedded devices and it works very good. You can see them at www.control.de (EDSP and TRZB) if you want. Questions 1: I didnt find out how to put the DOS mbr, delivered with SYSLINUX, to my bootdevice. What is the right command? Question 2: When I want to use PXELINUX with a BIOS that does not support Network boot via PXE is it possible to

I have a ZFS pool that has been corrupted. The pool contains a single device which was actually a file on UFS. The machine was accidentally halted and now the pool is corrupt. There are (of course) no backups and I''ve been asked to recover the pool. The system panics when trying to do anything with the pool. root@:/$ zpool status panic[cpu1]/thread=fffffe8000758c80: assertion failed:

That's a fake Block0 of an Apple Partition Map. Part of mjg's layout. Caused by isohybrid option --mac or xorrisofs option -isohybrid-apm-hfsplus. * Fedora has it with EFI FAT filesystem in one partition

Hi! I have bootable (USB flash) disk, that _appears_ to be using syslinux. (the word syslinux is in the PBR, in the hexdump). How can I chainload it? The payload seems to be a file that I tried load with COMBOOT, COM32 etc, but nothing works (they report that the file is not in proper format, wrong magic number or simply crash). How to proceed? is there a 100% way to confirm that it is really
