I have a question that has been puzzling me for some time ... what is the reason RedHat chose to go with btrfs rather than working with the ZFS-on-Linux folks (now OpenZFS)? Is it a licensing issue, political, etc? Although btrfs is making progress, ZFS is far more mature, has a few more stable features (especially Raid-z3) and has worked flawlessly for me on CentOS-6 and Scientific Linux-6.

Hello All, Just a short note to add my vote for a HUGE round of applause to the CentOS team for their untiring efforts in getting releases out the door. I've just upgraded several servers to 5.6 and it all "just works". None of the team's work is easy to accomplish, especially when less-than-useful complaints keep popping up from thoughtless users who don't appreciate

Hello all, I'm having quite an interesting time getting up to speed with KVM/QEMU and the various ways of creating virtual Guest VMs. But disk I/O performance remains a bit of a question mark for me. I'm looking for suggestions and opinions .... This new machine has tons of disk space, lots of CPU cores and loads of RAM, so those are not issues. I currently have several software

I think it depends on who you ask. Facebook and Netflix are using it extensively in production: https://www.linux.com/news/learn/intro-to-linux/how-facebook-uses-linux-and-btrfs-interview-chris-mason Though they have the in-house kernel engineering resources to troubleshoot problems. When I see quotes like this [1] on the product's WIKI: "The parity RAID code has multiple serious

Hello list members, In CentOS-5.5 I'm trying to achieve static assignment of SCSI device names for a bunch of RAID-60 drives on a Supermicro motherboard. The "scsi_id" command identifies all drives ok. The board has one SATA controller and three SAS/SATA controllers ... standard on-board ICH-10 ATA channels, an on-board LSI SAS/SATA controller, and two add-on SAS/SATA

hi all, I am hoping to move roughly 1TB of maildir format email to ZFS, but I am unsure of what the most appropriate disk configuration on a 3510 would be. based on the desired level of redundancy and usable space, my thought was to create a pool consisting of 2x RAID-Z vdevs (either double parity, or single parity with two hot-spares). using 300GB drives this would give roughly 2.4TB of usable

Hi, I have a small question about the depth of scrub in a raidz/2/3 configuration. I''m quite sure scrub does not check spares or unused areas of the disks (it could check if the disks detects any errors there). But what about the parity? Obviously it has to be checked, but I can''t find any indications for it in the literature. The man page only states that the data is being

Hi folks, I always wondered why there is no "metaflac --show-all-tags", in parallel to --remove-all-tags. Attached you can find a patch for your consideration. Sample output: % metaflac --show-all-tags *.flac 01 Pigs on the wing (Part One).flac:ARTIST=Pink Floyd 01 Pigs on the wing (Part One).flac:TRACKNUMBER=01 01 Pigs on the wing (Part One).flac:ALBUM=Animals 01 Pigs on the wing

"Does raidzN actually protect against bitrot?" That''s a kind of radical, possibly offensive, question formula that I have lately. Reading up on theory of RAID5, I grasped the idea of the write hole (where one of the sectors of the stripe, such as the parity data, doesn''t get written - leading to invalid data upon read). In general, I think the same applies to bitrot of

Hi, i''m new to the list so please bare with me. This isn''t an OpenSolaris related problem but i hope it''s still the right list to post to. I''m on the way to move a backup server to using zfs based storage, but i don''t want to spend too much drives to parity (the 16 drives are attached to a 3ware raid controller so i could also just use raid6 there). I

Hello, I have weight and wing length data of 5 kinds of birds (B1 to B5). Weight data (predictor) and wing data (response) were used to generated a simple regression. (using lm) Now some weight data are found but without wing data (B6, B7). I want to use the generated simple regression to produce wing data of B6 and B7 by their weight data. Please kindly advise R code to carry it out. Thank you.

Hello I want to predict wing length using regression commands. (lm and predict) The data details are as followed Data: Bird physiological data 1. body mass 2. body length 3. wing length Data type: Order A: consisting of 20 species, body mass and length of all 20 species are measured Order B: consisting of 2 species, body mass and length of only 1 species is measured Order C:
