很可能btrfs正在跳过损坏的数据，但是内核在放弃之前仍然尝试访问损坏的驱动器一段时间。根据：https://su...
Hi. Sorry if this is a duplicate, but I wasn't able to find issue on this. I'm using RAID1 on 5 drives, all of the drives were 3 TB. Recently I've had to switch a failed drive to a 4 TB one. And only then I noted, that btrfs balances based on unallocated space on the ...
A: Create a snapper configuration for each data drive you want to usesnapraid-btrfsfor, and make sure to setSYNC_ACL=yesin addition toALLOW_USERSorALLOW_GROUPSfor the user(s) and/or group(s) which will run snapraid-btrfs in your snapper configurations. You may wish to make a snapper te...
For example, a SSD drive can remap the blocks internally to a single copy--thus deduplicating them. This negates the purpose of increased redundancy and just wastes filesystem space without providing the expected level of redundancy. The duplicated data/metadata may still be useful to statisticall...
Features that are typically enabled on a mounted filesystem, eg. by a mount option or by an ioctl. Some of them can be enabled early, at mkfs time. This applies to features that need to be enabled once and then the status is permanent, this does not replace mount options.quota(kernel...

Devices can be of different sizes. However, if one drive in a RAID configuration is bigger than the others, this extra space will not be used. Someboot loaderssuch asSyslinuxdo not support multi-device file systems. Btrfs does not automatically read from the fastest device, so mixing differen...
(/dev/sdd) because it makes me feel a little safer using a separate hard drive for filesystem testing. You can use any hard disk on your PC that has enough free space to play with, and 50GB gives you plenty of room to do mad Btrfs experiments. Do be careful to not destroy ...
Currently the last drive that was detected will get this link. This is not btrfs specific at all. If mutiple devices share the same property that is used to build alias, only one device will get alias. What exact problem are you trying to solve? Author AndreaPro commented Dec 30, 2020 ...
