just to see if there any audio:
ffprobe -i in.mp4
find string as example here: Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 95 kb/s (default)
then exctract it
ffmpeg -i in.mp4 -vn -acodec copy out.aac
ffmpeg –help

If the drive should be replaced, then
1. start with determining which one is broken. See details of md device
# mdadm –detail /dev/mdX
# smartctl -a /dev/sdY
smartmontools required to be installed
2. replace required drive physically
3. See if the drive appeared
# lshw | grep /dev/sd[a-z]$ -A 3 -B 3
4. Careful! Transfer partition information from working disk to new installed disk
# sfdisk -d /dev/SOURCEDISK | sfdsik /dev/TARGETDISK
if source disk is sda for example, target sdb, then:
# sfdisk -d /dev/sda | sfdsik /dev/sdb
5. add partitions to md drives
# mdadm /dev/mdX –add /dev/sdY1
6. enjoy to watch progress of rebuild
$ watch -n 10 cat /proc/mdstat
7. If failed drive is not removed automatically from mdadm configuration, remove it by “–remove” command. It might require to set that drive failed, read man mdadm how to do it.
8. If mdX device is bootable device, then it is needed to cause system to boot from devices in mdX. In case grub is used, then:
# grub-install /dev/sdY
The best rdp client on linux I found to work is the freerdp
usage from console:
$ xfreerdp /u:lamer /w:1024 /h:768 /v:1.2.3.4:13389 +clipboard /a:drive,home,/home
Simple options that required mostly:
/v:<server>[:port] Server hostname
/port:number Server port
/w:<width> Width
/h:<height> Height
/size:<width>x<height> Screen size
/f Fullscreen mode
Clipboard Redirection: +clipboard
Drive redirection will make a “home” named network disk on the server machine:
Drive Redirection: /a:drive,home,/home

changing drives to bigger once caused to create new md raid device for copying files from old md4 to new md127 device. After that should the md4 physically removed and md127 renamed to md4 for other settings compatibility.
first unmount all md devices, then stop md raid:
#mdadm –stop /dev/md127
now rename device (for new meta 1.x, if older, might not work)
#mdadm –assemble –update=name –name=2 /dev/md4 /dev/sdc1
On debian jessie also initramfs should be updated to not to cause old name after reboot:
#update-initramfs -u
now try to mount device and add missing drive to md array.
