oops .. forgot about this post Checked backed up, changed the sata cable then clicked (repair) about 2 seconds later System Health Good

Seems now that I can only boot USB from within Bios? better either get that Disk 7 out test/reformat/reinstall or replace it then click (repair) again? Wonder if I just put Disk 9 in it's place?

Disk7 is now available to become a hot spare? but is still shown as "System Partition Failed, Normal" in HDD/SSD and System Health/Storage Manager wants to do a repair?

Further info Disk 7 Storage Manager / HDD/SSD : System Partition Failed, Normal Storage Manager / Logs : Disk 7 Had 26 events in May/June 2021 13x I/O errors 9x An I/O error occurred with the hard drive 3x Trying to reconnect to disk could this been a sata cable connection issue?

Hi DS3615xs - DSM 6.1.7-15284 Update 3 with 8xHDD's in raid5 with HDD9 as spare HDD7 totally disappeared from my system as my PC case is hard to access I left HDD7 in situ & did a repair with HDD9 as hot spare ... took about 8 hours & all came up good but on reboot a few days later HDD7 has re-appeared causing: "! Attention - System is healthy.Failed to access the system partition. Please repair it by clicking the following link.(Repair)" As the "System is healthy" & I don't know HDD7's reason for doing a Harry Houdini .. if I Shut Down .. remove HDD7 .. & reboot will all be back to normal?

Storage Manage -> RAID Group -> DSM Help ( within my system) ```````````````````````````````````````````````````````````````````````````````````````````````````````````````````````` I used this as a guide to Expand To expand the size of a RAID Group You can expand the size of a RAID Group by replacing existing hard disks with ones of larger size or by adding hard disks. Note: To expand a RAID Group with 3 TB or larger disks, make sure your RAID Group was created using DSM 3.0 or later. To expand a RAID Group by replacing existing hard disks with ones of larger size: You can expand a RAID Group by replacing existing hard disks with ones of larger size in the following RAID types: RAID 1 RAID 5 RAID 6 RAID 10 RAID F1 Associated volumes or iSCSI LUN on RAID Group for single volume or iSCSI LUN will be expanded automatically. Please follow the steps below: Turn off your Synology NAS. You can skip this step if your model supports hot-swapping. Replace one hard disk with another of larger size. Turn on the Synology NAS and repair the RAID Group. Repeat step 1 to 3 until all hard disks are replaced with ones of larger size. The system will expand the RAID Group automatically. Note: All services of Storage Manager will be temporarily stopped during the expansion process. You can only expand the hard disk when the RAID Group is in Normal status; otherwise it will cause data loss. If the RAID Group is in Degraded status, please repair it first. To expand a RAID Group by adding hard disks: This function is applicable with JBOD, RAID 5, RAID 6 and RAID F1 types of RAID. To do this: Select the RAID Group you want to expand. Click Manage. Select Add Disk. Follow the wizard to complete setup. Note: The RAID Group status must be Normal. For RAID 5, RAID 6 and RAID F1 types of RAID Group, the hard disk size must be larger than the smallest disk in the RAID Group. The status of the selected hard disk must be "Initialized" or "Not Initialized". ```````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````` So assumed I could use this guide to change Raid Type To change the RAID type of a RAID Group To change the RAID type of a RAID Group, there must be available hard disks installed on your Synology NAS. Currently, the following types of RAID change are supported: Basic to RAID 1 or RAID 5 RAID 1 to RAID 5 RAID 5 to RAID 6 Add mirror disk to RAID 1 Please follow the steps below to change the RAID type of your RAID Group: Select the RAID Group you want to change. Click Manage. Select Change RAID type. Follow the wizard to complete the process. Note: A RAID Group's status must be Normal before its RAID type can be changed. Otherwise data loss will occur. If the RAID Group is in Degraded status, please repair it first. To change a RAID Group's RAID type, enough hard disks must be installed on your Synology NAS, and the size of the new disk must be larger than the smallest disk in the RAID Group. The status of the new disk must be "Initialized" or "Not Initialized". The RAID type of a RAID Group with multiple RAID Arrays cannot be changed.

My Volume is Raid 5, it was at 81% usage - right now it's expanding from 7 to 8x 4TB hard drives (84%@50Hrs) the UI appeared to show that raid 5 -> raid 6 was just as easy as expanding .. but I assumed this would need raid hardware I'm not command line nor technically savvy

Can I change from Raid 5 to Raid 6 without any major issues? my system DS3615xs - DSM 6.1.7-15284 Update 3 hardware - i7 3770K/P8Z77-V pro (8 sata board)/8Gb ram with 1x LSI SAS 9201-8i 8x 4TB hard drives in raid 5 & 2x 250GB SSD's cache (at present 6 sata's go to MB & 4 sata's to LSI card) I wanted to add an extra (9th) 4TB HDD for the extra parity, but I've read somewhere that raid 6 needs to run off hardware raid & whereas raid 5 can run off software raid ?

finally got the two 225 rpm fans (Hyperborea) up over 600 rpm by using bios, they exhaust top-back & back but had to put a diode & a splitter to slow up the two front intake fans (Gentle Typhoon), this got them down to about 900 rpms ambient is 21°C & HHD's 25°-27°C idle

All went great .. the system is now a lot snappier only problem is noisier fans that will either work at about 225 rpm or 1550 rpm and nothing inbetween .. I'll look for a manual controller

In the DSM's Control Panel / General / Thermal status .. it has always had a dot & normal highlighted in green, and hovering the mouse over it always shows 40 °C/ 104 °F .. doesn't matter if the CPU is idle or busy So is there any way to get any live or real temperature of the CPU etc? and would it show or indicate anything if the CPU or MB etc got hot or overheated?

Thanks I used "usbview.exe" from Windows Kits Debugger for the VID & PID 1- Did a image backup of my Kingston Data Traveller bootloader with Alex's "USB Image Tool" 2- Mounted image with "OSFMount" 3- Only edited the VID & PID in the grub.cfg file using "Notepad++" 4- Burnt image backup to new Samsung Fit Plus 3.1 with "Win32 Disk Imager" Everything is working good I'm now swapping out the Q6600/GA-P35-DS3P/4 Gb ram for a very lightly used i7 3770K/P8Z77-V pro/8Gb ram the i5 4690/Asus Z97-K got taken by OMV

Thanks .. I'm running DS3615xs Jun 1.02b loader; DSM 6.1.7-15284 update 3 I've been using a Kingston Data Traveller 3.0 for a few years now and I just want to have my boot loader on a different USB stick so I was just trying to work out how to or when to change the VID & PID ?

I did a image back up with Alex's "USB Image Tool" .. to but can't work out how to change the vid/pid in the grub. is this done after Win32DiskImager? Also I couldn't do an image backup with Win32DiskImager?

For anyone researching this the answer to my questions is YES I removed them from the M/B's sata connected them in any old order through the LSi SAS 9201-8i card They showed up fully working
