Top shows brtfs-cache-1 and brtfs-endio-met while the hard drives seem busy
Hi, I have setup about a year ago a BTRFS RAID 1 filesystem on two 2TB Western Digital WD20EARS hard drives and I have created subvolumes that I mount regularly as I need them. I put mostly music, videos and various files on them as well as some Git bare repositories for my work files but for the last couple of weeks, there seems to be some activity happening on the drives for a few minutes and the following processes are showing up while this happens: brtfs-cache-1 and brtfs-endio-met. It seems that brtfs-cache-1 is more ''busy'' than brtfs-endio-met but after a while everything seems fine again. Is there anything I should worry about? I will soon do a full backup on ext4 just to make sure I don''t loose anything but is there any checks I can run on the drives to make sure everything is fine both on a hardware standpoint and on a data integrity standoint? Thank you for your help, All the best, Laurent -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at vger.kernel.org/majordomo-info.html
