Hallo zusammen,
ich betreibe eine DS710+ und habe das System nun mit einer DX510 erweitert. Leider habe ich hier arge Probleme. Ich habe eben ein Ticket an den Synology support geschrieben aber evtl. hat hier ja jemand ebenfalls eine Idee oder ähnliche Erfahrungen gemacht. Für Ratschläge wäre ich dankbar:
Folgendes Problem liegt vor:
The DX510 is connected to a DS710+ unit. Volume 1 is installed on the DS710+ (Raid1 mode) and runs perfectly fine. I created two more volumes on the DX510. Volume 2 runs in Raid 5 mode (=4x Western Digital WD20EARS-07MVWB0; 2TB each; slot 2-5), volume 3 runs in basic mode (WD10EADS-00L5B1; 1TB; slot1).
I was experiencing problems since the beginning. After creating the volumes (including checking of the HDDs) I started to copy data on the two volumes, which was not problematic. The problems started, after rebooting the system. I attached a screenshot. The Diskstation was not able to correctly initialize volume 2 and 3 (volumes on DX510). The protocol says the volumes were removed and then inserted again. Then the volumes crashed. Volume 1 (DS710+ still works perfectly fine).
After a reboot of the system there are always two possiblilities:
a) problem as desribed above; volume 2+3 are still in status "crashed".
b) the system works fine and all three volumes are detected and operational. After another restart there is a 50:50 chance that the system crashs again or works fine.
I repeated these system reboots several times now and the connection to the DX510 is just not stable (sometimes volume 2+3 crash, sometimes not). The eSATA cable does not hang loose. The SMART status says there are no problems with the HDDs.
I now tested another eSATA cable (eSATA II; 3 Gbit/s). The DX510 did not automatically startup and needed to be started manually. The DX510 was then correctly detected as an external drive and the data of volume 2 and 3 (formerly crashed) were accessable again (raid 5 testing for consistency). The "eSATA LED" of the DS710+ was not blinking. I assume there is something special about the Synology eSATa cable which enables the Diskstation to better communicate with the DX510 expansion unit?
However, my best guess is that there is something wrong about the Synology eSATA cable (cable defect) which results in an instable connection between the two devices.
