Upgrade path question

[Cliff]

Hi All 

 

I did do a search for this but couldnt find a difinative answer.

I have a intel i3 running DSM 6.1.7-15284 update 3, all has bee working fine up until one of my PCIe sata cards threw a wobbly and disks went offline and back on line..

anyway card replaced and volume wiped and restored from backup (one of 3 volumes on NAS).

ever since then it has been very hit and miss with performance, webpace can be from instant access to over 2 mins to login, transfer speeds are all over the place too, some days good and some no access for long periods..Bottom line I would like to rebuild it... I cant from memory remember which boot loader usb I am running as currently the machine doent have a video card in it to see the boot up.. 

So the question is, can I create a 6.2x bootloader (ds3615xs) and boot and have access to my existing volumes (currently have 12 disks in the machine) kinda in place upgrade?

or should I just create a 6.2 boot usb and wipe the lot and recreate and restore data from backup?

Happy to do either as I cant find the cause of this slowness (all disks check out as far as I can tell so I dont think its a hardware issue)

And further to that what is the best boot loader currently that people are happy with?

 

thanks for taking the time to read my long winded message :-)

Seems that you can do it, but tel us ubout your hw, please. In addition, it is suspected that your disks are already failing.

I have 6x 256gb ssds in a radi array, 4x3tb spinning disks in a raid and 2 10tb in a mirror

all disks check out against 3rd party software when removed and checked for errors, did this and then rebuild each array and reloaded from backup

running an intel dp55wg motherboard with i3 dual core cpu and 8gb ram ssds are using onboard sata and both arrays are on marvell chipset pcie cards

had been running super fast until one pcie card failed and disks disappeared and came back since then its all been a bit of hit and miss as to weather i get a good connection or not

also have dual 1gb network cards in a LAG to a properly configured switch.

all disks are new or within 12 months old raid is through synology and not hardware level raid

 

I have the 6.2 loader and tried on a different system, all working fine, I may just go for a total rebuild and see what happens
