i am studying about raid partion.i am not able to understand RAID level 5.
below is excerpt taken from tutorial.
Quote:
Combines striping and parity. Data is written across all disks as in RAID 0, but parity data is also written to one of the disks. Should a hard drive failure occur, this parity data can be used to recover the data from the failed drive, including while the data is being accessed and the drive is still missing from the array.
are they trying to say that the will be one extra disk which contain all the data. let says there are 4 disk. out of 4 , 3 disk are used for storing data and 4th one contain all the data (data of disk 1 2 and 3).
so here 4 th disk is acting as a parity disk or extra disk . which can be access whenever any one disk got corrupted.
please let me know if my understanding is correct or not , if not pls explain me what does raid 5 means then
Regards,
Scriptor

It looks like it was just set up in default configuration with a small boot partition and one huge partition for the rest, which composes a LVM volume.
