comment Why am I still getting a password prompt with ssh with public key authentication?
I have same issue. Yesterday, I issued rsync -av ./root/ root@THE_HOST:/root to upload some files from my local working directory, then, this issue occurs (in fact, at first I didn't notice it. After cron jobs in other hosts fails in the next morning, I started digging the reason). The rsync -av ./root/ root@THE_HOST:/root command changed the owner and permission of the /root directory of the remote host. Fixed the permission, problem solved.

comment Cannot start Wifi Hotspot from Fedora 20 - MATE but works on GNOME
in my experience (after search a lots web pages), you need to turn wifi off in NetworkManager, then execute rfkill unblock wifi, then start hostapd. The reason is wpa_supplicant is fighting with hostapd for seizing the wireless device. >> nl80211: Failed to set interface wlp3s0 into AP mod

comment Two arrays have slightly different array size with same size disks/partitions, why?
I'm not sure if it's the write intent bitmap caused the difference, highly doubt it (because it will not take many spaces). I asked same question in linux.raid mailing list, Mikael Abrahamsson guess it's because of different data offset, which I believe it (but still no explanation for it). spinics.net/lists/raid/msg46175.html

comment Two arrays have slightly different array size with same size disks/partitions, why?
I just did a quick RAID creation test on loop devices in CentOS 6.5 (mdadm v3.2.x) and Fedora 20 (mdadm v3.3), found out that it's not the size overhead of RAID 6. Size of RAID 5 & RAID 6 are identical in same OS, but they are different between CentOS and Fedora. Test script: MAKEDEV /dev/loop; truncate -s 10M hdd5{1..5} hdd6{1..5}; for hdd in {1..5}; do losetup /dev/loop5$hdd hdd5$hdd; losetup /dev/loop6$hdd hdd6$hdd; done; mdadm -C /dev/md5 -l 5 -n 4 -x 1 /dev/loop5{1..5}; mdadm -C /dev/md6 -l 6 -n 5 /dev/loop6{1..5}; mdadm -D /dev/md5; mdadm -D /dev/md6
