Pegasus R6 Drivers

Hi,

same problem

I received that RAID 4 12/212011

hey do not say it takes 10 to 14 hours to format .

Even for Raid 4 they are talking about Raid 6 format with spare disk

which does not even exists .

I only see it on 4 big disk Lacie where you can see the 4th waiting

I cannot find any explanation

Promise does not even answer the questions

They just get the money and that's the end of the line for them

Next time I stay away from Promise stuff

I go back to Lacie . They are not much better as persons

but at least their progs function nearly correctly

By the way I am on Mac OSX Lion 10.7.2

Better luck next time

HI bikkuri,

You must have been lucky, I am still expecting 3 answers from Promise .

To answer your message :

The Promise manual can be understood by people who does not need the manual anymore .

It is not clear in any way . Uou cut it in 4 and take it with you to rhe right place it belongs

Even on a RAID 4 when you are lucky enough to get the wizard working, it proposes and accept a Raid 6

I was convinced and abused, because I also own a 4Big LaCie with 4 disks. When you format in Raid 6, the 4 th led is blinking amber and 3 others blue and the manual tells that the 4 th disk is waiting in case of trubble to take over and solve the problem .

The R4 *might* support RAID-6 but since RAID-6 is double parity - that means two of the four drives would be partiy drives - meaning only two data drives. I would think you would be better with Mirroring - two data drives mirrored to two spare drives.

Or RAID-5 with a spare - only one parity drive - but a spare to rebuild onto.

I just setup my R6 and wondering why they preconfigured for RAID-5 with no spare. Sure you get 2TB more useful space out of it - but if a drive fails you run in degraded mode until you acquire a replacement drive - and if a second drive fails before you get the replacement drive in then you lose everything.

I suppose that would be the only benefit of RAID-6 on 4 drives - instead of needing to rebuild the failed drive before you lose a second - you could have two drives fail and not lose data - with mirroring you would only lose data if you lost both copies of the same disk.

About half the purpose of my unit will be as a backup drive (split between my local backup of 5 or 6 systems plus remote offsite target for a number of others) so temporary loss of data would be mostly an annoyance - still having a spare to rebuild onto while a replacement drive is procured saves time and hassle.

RAID-6 is used on larger disk arrays in part because the rebuild time of a full 2TB drive and the stress on the rest of the drives during rebuild can result in a double drive failure.

The 127.0.0.1 mapping to my host name suggestion worked for me.

Hi, About Pegasus Raid again .

I am just a regular very normal user . In their user manual they throw figurs, bunches of expressions that average people cannot understand . Examples :

SMART POLLING INTERVAL 1 to 1440 minutes what is the best and reason .

WRITE BACK CACHE FLUSH INTERVAL 1 to 12 what does oit mean and what is best ?

ENCLOSURE POLLING INTERVAL 15 to 255 what for ?

LOW MEDIUM HIGH

REDUNDANCY

REBUILT RATE

TRANSITION SETTINGS

PDM SETTINGS

SYNCHRO SETTING

Not one explanation of the benefits of one way or the other .

TCQ NCQ what is it and what use, in which case

STRIPE SIZE 64K to 1MB what is it and what use, in which case

SECTOR SIZE 512 B TO 4 KB what is it and what use, in which case

Quite often the dive does not feel like restarting for a dozen trials, tha marathon cables have to be inverted.

So says the guy at Promise . Sometimes, the computer announces that Promise Utilty cannot start beacuse a certan daemon is not present . PKG has to be reloaded .

In a few words, PEGASUS RAID is anything you want, BUT CERTAINLY NOT SAFE FOR ONE SECONDE
