Parity check completed successfully! So i guess that you were right - it must have been the SATA card, Thank you. I've attached the logs - hopefully all good now? Am I fine to acknowledge the UDMA CRC errors on Drives 3 and 4? Thanks again for you help, much appreciated 👍 syslog-192.168.232.133.log

Hmmm, sorry about that. Running parity check again. Will post again when it either fails or completes.

Hi, so replaced the SATA card with the one above. Now Parity check doesn't cause Unraid to crash, but the Parity check aborted around the 7-8% mark. unraid-diagnostics-20200126-1237.zip

Cool, thank you for your help 👍 will look into it, will replace with this: https://www.amazon.co.uk/gp/product/B07X21J35K/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Would this be suitable? https://www.ebay.co.uk/itm/LSI-Logic-MegaRaid-SAS-8708EM2-SAS-SATA-RAID-Controller/372924841101

I have x6 SATA ports on my motherboard and a x4 ports on a PCI-E card (AC1539). I don't have enough ports on the motherboard for all my drives, should I be using a different type of card? Am happy to to try - but like I said in my original post have had this current server for 2 years without issue and a the same drives in a previous self build for 3 (using the same PCI-E expansion card) <<< obviously not the two drives (3 and 4) which I recently replaced.

Apologies, please find logs attached. syslog-192.168.232.133.log I recently had to replace x2 drives as they failed. I have dual parity drives and the data rebuilt no problem. There was a period a couple of days ago when the Ethernet switch my Unraid server is connected to stopped working (have since replaced it) - the server did not have network access for about 12 hours - don't know if that could be related... Now I'm noticing that both drives I replaced are throwing UDMA CRC errors, every time Parity check fails and it crashes the error count goes up (see screenshot). Both drives were pre-cleared without issue and had been working fine up until now.

Hi I'm a newbie, well, I've been using Unraid for a couple of years without issue. Unraid v6.8.1 is crashing 0-3% into Parity check. I don't know what's causing the issue, can anyone help?

Maybe probably not the place to ask, so don't shoot, but(!)... just wondering when you guys plan to implement support for Samba 4.8, the current stable release, released on March 13? https://wiki.samba.org/index.php/Samba_Release_Planning I ask as it fixes this bug: https://bugzilla.samba.org/show_bug.cgi?id=12380 and would enable TimeMachine over smb? Thanks!
