Tænkte det nok. Så det vil sige at jeg har ødelagt mit raid?
Det vil også sige, at man IKKE skal defragge RAID setups? Hvordan holder man det så "rent" ?
Beklager jeg ikke googlede noget før. Man skal åbentbart defragmentere RAID setups:
"In the case of RAID or SAN, it is indeed likely that a file that defragmentation software makes logically contiguous will be physically fragmented by the disk controller software. This is OK. The user benefits here in two ways. First, the file system is able to access the file in a single logical I/O taking the minimum elapsed time and using scant CPU and memory. Second, the file is in the best possible place for physical access according to the disk controller’s intelligence.
In 2002, Raxco Software worked with Compaq Computer’s High-End RAID Group to determine what effect defragmentation might have on large RAID configurations. Compaq tested on a machine using the faster processors, the maximum amount of memory, and the fastest disk speeds. The idea was to isolate any performance change to disk I/O. The tests were measured using ZD’s Server Bench and Intel’s IOMeter benchmarking tools. The results showed that defragmentation could improve disk I/O by 50%."
