Back story: I started my pool with a 200gb partition at the end of my drive (sdc5) , until I was able to clear out the data at the beginning of my drive. When I was ready, I ran `btrfs dev add /dev/sdc4 /` then `btrfs dev del /dev/sdc5 /`, $ sudo btrfs fi resize max / Resize ''/'' of ''max'' ERROR: unable to resize ''/'' - Invalid argument in dmesg i see: [   72.729685] btrfs: resizer unable to find device 1 $ sudo btrfs fi df / Data: total=34.00G...

Hi, I have been attempting to set up a multi-boot USB stick (i.e. multiple bootable ISO images on the one stick) I have had good success by: - processing ISO with isohybrid (with "partok" flag) - dd'ing ISO to primary partitions on the USB stick (e.g /dev/sdc2, /dev/sdc3, /dev/sdc4) - installing grub to USB stick and configuring to chainload to these partitions To remove the limit of 4 partitions, I would like to do the above but utilise logical partitions. All my tests to do this have failed, and generally result in the error message "isolinux.bin missing or corrupt.&q...

...(32+20)(%si), %ecx movl (36+20)(%si), %ebx The start LBA of a GPT partition entry is an 8 byte number stored at offset 32.

...boot loader? /dev/sdc? is MBR (the default with Centos) enough 2. Is it necessary to have GPT label and EFI on /dev/sdc? 3.

To my knowlege, a root file system of size 64GB should be handled peacefully by centos.

You probably mean this line: memcpy(mbr, &isohdpfx[hd0 + 3 * partok], MBRSIZE); The indize do not apply to bytes but to byte arrays of size MBRSIZE. extern unsigned char isohdpfx[][MBRSIZE]; (hd0 + 3 * partok)

Yes, these are my thoughts as well. I think the jump from GRUB to the isohybrid code on the logical partition is working fine, but when the isohybrid code is trying to jump to

...t if you want to have several, this is how I do it: 1. grab the syslinux distribution you want to use--probably the latest is best. Create a bootable USB from this distribution. If the USB is /dev/sdc, you should be able to use: # mkdiskimage -4 /dev/sdc 0 64 32 # syslinux /dev/sdc4 2. mount the USB and create a directory on it. I use the name 'sysl_files'. copy all the *.com, *.c32 and memdisk from the distribution to the 'sysl_files' directory. You might want to add the *.bin files as well, just so you'll have easy access to them if y...

I assume it's not possible to store a copy of the LDLINUX.SYS binary at the end or inside of either ISOLINUX.BIN or LDLINUX.C32 then? Then at least it could be extracted, for those distributions not having LDLINUX.SYS / SYSLINUX(64).EXE present on their CD. Having
