"EDD Load error" on btrfs, how to debug?

I'm not sure why granularity finer than 1MiB is necessary. But setting that aside, with a rotational drive with 4KiB sectors, you're better off with 1MiB alignment than not being 4KiB aligned at all. Depending on the drive and workload misalignment can cause a brutally bad performance hit. And if it doesn't then I wouldn't worry a...

...out something like this using sda and sdb. Create /boot as 512 MB XFS raid1 array. Create SWAP as 32 GB SWAP raid1 array. Create / on 3.xxx TB XFS raid1 array. I then get error. "Your BIOS-based system needs a special partition to boot from a GPT disk label. To countinue, please create a 1MiB 'biosboot' type partition." I cannot seem to create the biosboot partition so it is mirrored to both drives for redundancy. Any ideas how to do this? I want everything mirrored to both drives.

isohybrid and ISO images whose size is not a multiple of 2048 bytes vs. VirtualBox
...ttps://tails.boum.org/ > [details] https://labs.riseup.net/code/issues/8891#note-9 > > Cheers, > -- > intrigeri Any (common) ISO image size should be a multiple of 2048 bytes, as this is the normal bytes_per_sector value. For isohybrid images, the result should be a multiple of 1MiB (1048576 bytes), which is itself a multiple of 2048 bytes. So, in addition to adding the corresponding MBR and partition table to the original ISO image, the isohybrid tool should also check that the ISO image is a multiple of 1MiB. If it is not, then the isohybrid tool should first add a &quo...

[MC] Questions about relaxation in MC
...branch target is out of range, LLVM MC will issue an error message to tell users it could not resolve the fixup record. I have compared the result with the GNU assembler. GNU assembler will convert the branch to inverted one plus jump to make the branch possible. The range of unconditional jump is 1MiB. It looks like ########################## bne a0, a1, FAR_BRANCH … FAR_BRANCH: converted to ########################## beq a0, a1, SKIP_J j FAR_BRANCH SKIP_J: … FAR_BRANCH: I found there is a target hook, relaxInstruction, that tries to achieve the similar goal. However, the target hook only re...

isohybrid and ISO images whose size is not a multiple of 2048 bytes vs. VirtualBox
Hi, at [Tails] we're in the process of shipping hybrid ISO images by default again. We're using `isohybrid -h 255 -s 63' to do that (thanks to the advice we got on this mailing-list a few months ago!). And then, we've discovered that sometimes, isohybrid produces ISO images whose size is not a multiple of 2048 bytes. Who cares? ... may you ask. Well, apparently, VirtualBox does:

OT - parted guidance
parted fs resize is deprecated. http://savannah.gnu.org/forum/forum.php?forum_id=6837 parted fs move can only move a partition into free space https://www.gnu.org/software/parted/manual/html_node/move.html The thing to do here is use gparted live or Fedora live media and yum/dnf install gparted. It has a move/resize option that will do what the OP wants. Chris Murphy

Hello Everyone, I am a newbie. When I try to install GRUB2 on centos 5.2 system, I get following error. centos5: grub-install /dev/sda //sbin/grub-setup: warn: This GPT partition label has no BIOS Boot Partition; embedding won't be possible!. //sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE

partition offset/alignment on SAN devices.
Hey folks, I've been getting requests from the users that they want the OCFS2 filesystems aligned to 64k boundaries, however, when I began the project, the dummy of me, created the OCFS2 filesystem on top of the whole disk device (no partition) for example, one of the SAN devices would show up as /dev/dm-10, I created the filesystem using the following command: mkfs.ocfs2 -L SOMELABEL

isohybrid and ISO images whose size is not a multiple of 2048 bytes vs. VirtualBox
...the difference, in bytes, between the non-hybrid ISO image and > the isohybrid one? Could you please provide both exact sizes? Our current stable release [1], which wasn't a hybrid ISO, is 951764992 bytes. If I run `isohybrid -h 255 -s 63` it becomes 954132480 bytes which is a multiple of 1MiB (and hence 2048 bytes too). This seems to happen for all of our stable releases I tried, and they're all below 1GiB in size...

Samba over slow connections
Hi list (and happy new year), I'm experiencing some troubles using Samba (4.1.17 debian version) over VPN. Basically we've following setup : PC === LAN ===> VPN (WAN) ==== LAN ===> Samba file Server Copying big (say > 1MiB) files from PC to Samba file server almost always ends up with a NT_STATUS_IO_TIMEOUT error (or "a network error occured" if trying to copy from a Windows box). It seems that Samba cannot cope with the fact that LAN speed is way higher than WAN one (thus filling buffers an not waiting...

But we now have a report about failure of 255x63 on a popular pseudo-hardware, when the ISO is presented as DVD-ROM. (Probably there is no complaint when it gets presented as hard disk.)
