booty

Thx for your answer. I got a UPS and my NAS is powered over UPS. Yesterday i installed the latest XPEnoboot_DS3615xs_5.2-5967.1 Till now no problems. So same behavior like the DSM 6.1.4-15217 Update 5 without modified lzma. Why this didn't happend with these Releases?!

DSM: DSM 6.1.4-15217 Update 5 Model: DS3617xs Hardware: ASROCK Q1900-ITX, 4GB RAM Install Type: Baremetal NIC Model: Intel E1000 Storage: HighPoint RocketRAID 2720SGL Issue: You are not authorized to use this service. I have 2 disks on mainboard and 3 disks on the HP RR 2720SGL. With the original extra.lzma the 3 disks are not detected. So i read a little bit in this great forum and found an thread where i downloaded extra3617_v4.5 because on user had the same problem with not detected disks with these controller. original lzma lspci -k | grep 'Kernel driver' Kernel driver in use: ahci Kernel driver in use: xhci_hcd Kernel driver in use: pcieport Kernel driver in use: pcieport Kernel driver in use: pcieport Kernel driver in use: pcieport Kernel driver in use: e1000e Kernel driver in use: r8168 extra3617_v4.5 lspci -k | grep 'Kernel driver' Kernel driver in use: ahci Kernel driver in use: xhci_hcd Kernel driver in use: pcieport Kernel driver in use: pcieport Kernel driver in use: pcieport Kernel driver in use: pcieport Kernel driver in use: mvsas Kernel driver in use: e1000e Kernel driver in use: r8168 It seems the mvsas makes the difference. With the original lzma only my 2 drives are detected and all is fine over days. With the extra lzma all drives are detected but 1-2 per hour i got the message in the web gui "You are not authorized to use this service. " and the logs say Improper shutdown. When this happend all services are down. Unfortunately i cant say if the synology really reboot. 1 Note: During the installation i went into an mistake. I didn't know my mac from the e1000 and i thought i boot up the synology and show in the info tab. The MAC in the info tab is a synology mac. I changed the grub during boot on the command line. Yesterday i noticed these mistake and i corrected my mistake and changed also in the grub. But unfortunately these helped not and the improper shutdown comes again and again. I hope someone can give me some hints.
