Hi, Woke up this morning with a kernel panic (for which I do not have details). Please find below the output for btrfs check. Is this normal ? What should I do ? Arch Linux 4.2.5. Btrfs-utils 4.3.1. 17x4TB RAID10. Regards, Vincent [root@3dcpc5 ~]# btrfs check /dev/sdk Checking filesystem on

Re: Response to Bcachefs Claims

I'm still parsing through the multi-device advices. Will be back on this when I'm done. And I'll probably switch distro to Archlinux which seems the way to go if one is using cutting-edge kernel features like Btrfs. As for the work on Gotchas/Known Issues on the Btrfs wiki, I also think that

Response to Bcachefs Claims

Hi, I have been using Btrfs for almost a year now with a 16x4TB RAID10 and its 8x4TB RAID0 backup (using incremental snapshots diffs). I have always tried to stay at the latest stable kernel (currently 4.1.6). But I might be moving to Fedora 22 because Centos 7 has significant

Hi, I think I might be having this problem too. 12 x 4TB RAID10 (original makefs, not converted from ext or whatnot). Says it has ~6TiB left. Centos 7. Dual Xeon CPU. 32GB RAM. ELRepo Kernel 4.1.5. Fstab options: noatime,autodefrag,compress=zlib,space_cache,nossd,noauto,x-systemd.automount

Hi, (Sorry if this gets sent twice : one of my mail relay is misbehaving today) 50% of the time when booting, the system go in safe mode because my 12x 4TB RAID10 btrfs is taking too long to mount from fstab. When I comment it out from fstab and mount it manually, it’s all good. I don’t like

Re: Send/Receive Use Case

actually I have another question : is it posssible for a RAID0 fs to “receive” from a “sending” RAID10 ? or do they need to be of the same replication scheme too ? On Jun 27, 2015, at 10:34 AM, Vincent Olivier vinc...@up4.com wrote: ok i’ll go home and rethink my life then ;) On Jun 27
