Urgent Problem i/o ;(

[javiercampos]

Is this a production server? or are you in testing phase? if testing you might try using raid 10 instead of raid 5. What disk controller did you say you were using and how much cache does it have. I am assuming your using Block I/O.

Running out of ideas as to what your issue might be :-)

Thanks for the reply.
Look at the raid card is:

LSI MegaSAS 9260

the issue that only allows me to do raid0, 1, 5 and 6 RAID10.
The other .. My storage has a capacity of 16 drives in raid1 2 are for the open-e system and I have raid5 array with 7 drives .. how rare such an arrangement of 7 discs I get the same performance as one with 3 disks.

and if I'm using Block I/O.
