StarTech.com 1.6 ft/50cm Serial Attached SCSI SAS Cable - SFF-8087 to 4 x Latching SATA Just purchased it

the link above http://lime-technology.com/wiki/index.php/File_System_Conversion#Mirroring_procedure_to_convert_drives does no longer work. Does anyone know where I cna find the guide, as I am looking to upgrate all my reiserfs drives?

I've used all four sata cables and need to buy another four, does anyone have a product recommendation?

Have not had a single warning since I plugged the rear fans in the motherboard. It has not been super hot but had a few warm days and it has held up well so far.

Thanks PeterDB. I have plugged the rear two fans directly in the the fan sockets on the motherboard and they immediately started spinning way faster than before, so I hope this will improve the airflow through the case. I receive email warnings when HDD reaches temps of over 45C, I will monitor that to see if there are any changes.

I have a Gigabyte G33-DS3R. Would your tutorial be applicable to this motherboard? Currently I can see under PWM controller: it8718-pwm1 it8718-pwm2 it8718-pwm3 If I choose the first and click on detect under PWM FAN it fills it in with this text /sys/devices/platform/it87.656/hwmon/hwmon1/fan1_input I have three NORCO s500 cases plugged in the power sockets currently (4 in the system), each one of them has hard drives connected to the motherboard and hard disk connector cards. Are those three above the fans of the NORCOs? Would seem like the CPU fan is not detected. I have not connected the two case fans yet to the motherboard, they are just hooked up to the power cable at the moment, will try connecting to the motherboard next

I guess you don't use getfancontrol on your unraid server?

These are the two fans at the back. I am pretty sure I have not even connected them to the motherboard so it might perhaps explain why they seem to move so litte air, and might be aggravating the heat issue https://www.quietpc.com/cl-swif2-12p

Also I replaced the Norco stock fans with the Coolink SWiF2-801 80mm 1500 RPM 3-pin Quiet Cooling Fan, I wonder if they can be run at full speed and how? Link to the fan product page https://www.quietpc.com/cl-swif2-801

Thank you Whaler_99, is it available as an application on Unraid? Also I am interested in setting up a target temperature for those hard disks that usually get hot, can I link it to hard disk temperatures? I didn't see that as an option in the video.

Well I am back in the thread. My setup is still working well with temperatures apart from summer. I have to stick a fan in front of the server to keep it cool, which is ok but not ideal, expecially when going away. I get a lot of drives going above 45C without the fan trick. I am tempted to replace the two big fans at the back, but I only want them to go full speed in summer, so I guess I am looking for a manual speed regulator instead of a fan that senses case temperature. Any suggestions?

Data rebuilt fine on a new drive, no errors, seems that the issue was with the old drive.

popped in another disk, rebuilding, let's see what happens

diagnostics also attached tower-diagnostics-20230304-1821.zip

Hi folks, I run out of space so I decided to used an old drive, which I added to the array. I have 4 Norco 500 in my server case, using two fully of them (10 drives) at the moment so I added the disc to an empty Norco. Unassigned devices reported 2 pending sectors, then pending sector returned to 0. I cleared the disk, formatted it and added it as drive 10. Then a while later reported read error, and 422 pending sectors which kept rising to 1455. I have attached a deep smart test, is the drive on its way or is an issue with the Norco, or an issue with the cable connection? Only this drive on the Norco cage and I am having these issues. tower-smart-20230303-2014.zip

No red X for me under Unassigned Devices. Stopped the array and added the drive, Disk-Clear started now.

It is filled with data so I guess it has a partition? Can I delete the partition and preclear?

mmh preclear doesnt see the drive, either mounted or unmounted in unassigned devices

Do I need to preclear an old drive, which I used in the unraid system, and then removed when upgrading the drive to a larger one, or just format it?

Hi there, I am planning to run 3 Norco ss-500 and I only have two cables with Molex connectors coming out of the power supply. I am using two molex per Norco ss-500, but as I don't have eough molex free for the third cage, I am planning to use a molex splitter and connect it to one of the two existing cables. Any objections, suggestions?

Yes I understand, but is there a science to this that can confirm how much do we need to leave? On my largets drive 10% is over a terabyte. How much free space does unraid need to rebuild a disk etc.

the link in is broken

oh boy, any suggestions, links for the xfs conversion

Hi everyone, this is really interesting. All of my drives are at 90% use, they range from 2 TB to 10 TB. I use the server as media repository for movies and tv series. Files are never changed, only added. Does that mean I can safely set the limit to 1%? This will not affect the server read performance? Don't really care much about the write side as I only write each file once. My free space currently is just under 5Tb. PS: my file system is reiserfs
