Hi there! I am new to the list, and to OpenSolaris, as well as ZPS.
I am creating a zpool/zfs to use on my NAS server, and basically I want some redundancy for my files/media. What I am looking to do, is get a bunch of 2TB drives, and mount them mirrored, and in a zpool so that I don't have to worry about running out of room. (I know, pretty typical I guess). My problem is, is that not all 2TB hard drives are the same size (even though they should be 2 trillion bytes, there is still sometimes a +/- (I've only noticed this 2x so far) ) and if I create them mirrored, and one fails, and then I replace the drive, and for some reason, it is 1byte smaller, it will not work. How would I go about fixing this "problem"? ****THIS is just a thought, I am looking for thoughts and opinions on doing this... it prolly would be a bad idea, but hey, does it hurt to ask?**** I have been thinking, and would it be a good idea, to have on the 2TB drives, say 1TB or 500GB "files" and then mount them as mirrored? So basically, have a 2TB hard drive, set up like: (where drive1 and drive2 are the paths to the mount points) Mkfile 465gb /drive1/drive1part1 Mkfile 465gb /drive1/drive1part2 Mkfile 465gb /drive1/drive1part3 Mkfile 465gb /drive1/drive1part4 Mkfile 465gb /drive2/drive2part1 Mkfile 465gb /drive2/drive2part2 Mkfile 465gb /drive2/drive2part3 Mkfile 465gb /drive2/drive2part4 (I use 465gb, as 2TB = 2trillion bytes, / 4 = 465.66 gb) And then add them to the zpool Zpool add medianas mirror /drive1/drive1part1 /drive2/drive2/part1 Zpool add medianas mirror /drive1/drive1part2 /drive2/drive2/part2 Zpool add medianas mirror /drive1/drive1part3 /drive2/drive2/part3 Zpool add medianas mirror /drive1/drive1part4 /drive2/drive2/part4 And then, if a drive goes and I only have a 500gb and a 1.5tb drives, they could be replaced that way? I am sure there are performance issues in doing this, but would the performance outweigh the possibility of hard drive failure and replacing drives? Sorry for posting a novel, but I am just concerned about failure on bigger drives, and putting my media/files into basically what consists of a JBOD type array (on steroids).
