similar to: To loop or not to loop with btrfs

Hallo, linux-btrfs, please delete the option "-L" (for labelling) in "mkfs.btrfs", in some configurations it doesn''t work as expected. My usual way: mkfs.btrfs -d raid0 -m raid1 /dev/sdb /dev/sdc /dev/sdd ... One call for some devices. Wenn I add the option "-L mylabel" then each device gets the same label, and therefore some other programs

I would like to have a smart cli tool, that shows a comprehensive list about the local storage structure: An output like: /srv /dev/mapper/luks-f85b7a2c-...: UUID="ca924fad-..." TYPE="ext4" /dev/mapper/vg_internal_e-lv_internal_srv: UUID="f85b7a2c-..." TYPE="crypto_LUKS" vg_internal_e /dev/md3: UUID="1Fi2Ex-..."

(Resend: message didn't show, was my original message too big? Posted one of the output files to a website to see) The point of RAID1 is to allow for continued uptime in a failure scenario. When I assemble servers with RAID1, I set up two HDDs to mirror each other, and test by booting from each drive individually to verify that it works. For the OS partitions, I use simple partitions and

I have been investigating pci pass-through for virtualized guests and the documentation I have found seems to me to lack a certain consistency in its example. This may be due to my not understanding what it is trying to inform me. What I wish to do is to configure a pci multi-port serial i/o card for use by a single virtual host. I start by running lspci -v on the host to identify the serial

Hello all, I have written a pass, which replaces condition branchinst using indirectBr to obfuscate program. The origin IR is as the following: br i1 %1, label %2, label %3 And the transformed IR is as the follwoing: %4 = select i1 %1, i8* blockaddress(@func, %2), i8* blockaddress(@func, %3) indirectbr i8* %4, [label %2, label %3] The pass's core function is as the

Hello, Does anyone have experience using a 3ware 9650SE series raid controller on CentOS 6.0? I am getting very sporadic throughput with moderately sized files (0.5-2GB) on ext3. I have tried most of the mount time tuning options: * noatime * trying different journal types * setting commit=120 - helped a little Even after these optimizations it doesn't seem like the raid array is working

Hi, I''ve some btrfs fs which are encrypted with loopaes. I decrypt them in a script during bootup. Now I want to determine if the decrypted fs is a btrfs fs.

I did now try many different drivers from different vendors none of them worked thus I think there is something else wrong. I then did some more tests, trying to find anything being

Hi, Adding bricks to a disperse volume is very easy and same as replica volume. You just need to add bricks in the multiple of the number of bricks which you already have. So if you have disperse volume with n+k configuration, you need to add n+k more bricks. Example : If your disperse volume is 4+2, where 2 is the redundancy count, you need to provide 6 (or multiple of 6) bricks (4+2 = 6)
