  1. Do you need to export the hashes to run a check? If not, does it just read each file and compare it to the extended metadata checksum?
  2. I just had the same error show up - I think you are correct ... it's a spin up / down error. Under certain conditions, unRAID will read a drive before it is ready and thus cause this error. According to the SCSI error code guide I found on Oracle's website, the following code in the logs: ASC=0x4 ASCQ=0x2 Logical Unit Not Ready, Becoming Ready Indicates that the drive is OK— it is in the process of spinning up, but it is not yet ready. https://docs.oracle.com/cd/E19105-01/storedge.6320/817-5918-10/817-5918-10.pdf I'm seeing the same error on my SuperMicro 847 chassis.
  3. This looks related to Same issue with a LSI HBA and LSI Expander...
  4. I'm having the same problem - actually lots of problems with a LSI 2308 HBA and a LSI expander ... there seems to be a lot of IO WAIT problems which manifests itself in different ways including interrupting a stream if a disk needs to spin up.
  5. I'm seeing this as well running the File Integrity Plugin - is there a way to raise it?
  6. I have a question - why does the "Build Up-To-Date" become green while the plug-in is still processing a drive? Basically it's only 20% of the way through processing a disk but "Build Up-To-Date" is already flagged as green? Also, the number of files processed also seems off. For example, the system says 97.9% processed, but the calculation doesn't seem ot make sense? Currently processing file 10284 of 14494 Is this correct? Lastly, why do renamed files create a new hash - shouldn't the old hash be maintined if a file is renamed? Thanks.
  7. The LSI 9207 does detect the drive as a SATA-SSD, does that mean it supports TRIM? If TRIM is not supported, can it be run manually via a schedule? Does that work or does it mean that even manual TRIM won't work on HBAs.
  8. I'm seeing this exact same error, but different sector on a few of my drives: Mar 12 17:22:28 merlin kernel: sd 10:0:3:0: [sdm] tag#0 UNKNOWN(0x2003) Result: hostbyte=0x00 driverbyte=0x00 Mar 12 17:22:28 merlin kernel: sd 10:0:3:0: [sdm] tag#0 CDB: opcode=0x28 28 00 82 52 40 27 00 00 08 00 Mar 12 17:22:28 merlin kernel: print_req_error: I/O error, dev sdm, sector 2186428455 In my case: [Sun Jun 23 13:05:35 2019] sd 1:0:28:0: [sdab] tag#18 UNKNOWN(0x2003) Result: hostbyte=0x00 driverbyte=0x00 [Sun Jun 23 13:05:35 2019] sd 1:0:28:0: [sdab] tag#18 CDB: opcode=0x28 28 00 00 01 62 c0 00 02 00 00 [Sun Jun 23 13:05:35 2019] print_req_error: I/O error, dev sdab, sector 90816 I don't think it's a disk failure ... but rather something to do with SMART or controller communication with the drive. When I had the unassigned plugin installed I was seeing a lot more of these errors. I think it's more of a compatibility issue than hardware error. The error above is from a Crucial M500 running off a LSI 9207-8i on a BPN-SAS2-826EL2 backplane.
  9. Same here on a SuperMicro with an onboard LSI 2308 ports w/ hard drives and a LSI 9207-8i with the SSDs. They are connected to BPN-SAS2-846EL2 expanders (24 port and 12 port). When mover runs, system grinds to a halt.
  10. Same here, upgraded to 6.7.0 and mover now causes Plex to hang, I noticed in TOP the IO wait time is through the roof when mover runs. IO Wait pegs out at 75 - 90%! I have two LSI cards on a SuperMicro BPN-SAS2-846EL2 expander, each card is connected to 2 ports on the card so there should be plenty of bandwidth. One LSI card is built into the motherboard (running of CPU PCIe) and second card is running off the 8x slot on the motherboard. I don't recall this happening on my older Celeron machine, it was running 6.6.x. Looks like others are having the exact same issue and the symptoms are identical, so that is good...
  11. Hi all, I recently migrated my setup to a SuperMicro SC847 chassis and a repurposed SuperMicro X10SLF motherboard. I noticed in the logs, I'm getting a lot of messages like: Jun 21 09:31:27 nasserv kernel: hpet1: lost 7 rtc interrupts Jun 21 09:31:28 nasserv kernel: hpet1: lost 1 rtc interrupts Jun 21 09:31:28 nasserv kernel: hpet1: lost 2 rtc interrupts Jun 21 09:31:28 nasserv kernel: hpet1: lost 5 rtc interrupts Jun 21 09:31:28 nasserv kernel: hpet1: lost 13 rtc interrupts Jun 21 09:31:28 nasserv kernel: hpet1: lost 15 rtc interrupts Jun 21 09:31:28 nasserv kernel: hpet1: lost 9 rtc interrupts I saw in another post that disabling ACPI may fix this? Is that the best way to resolve these messages in the log?
  12. When buying a Supermicro make sure you get a SAS2 backplane ... which yours has. Also, the EL2 model means it has dual port capabilities (i.e. 2 x SFF-8077 connectors), giving it a lot of bandwidth. You can connect either 1 cable to the card, 2 cables for double the bandwidth, or 2 cables to do different cards, cascade the controller to a real external port. Check the manual for different connectivity options. EL1 may or may not support dual link - people on the FreeNAS forums say it does unofficially. Also, make sure all the trays come with the chassis - they can add up quick. Also, that both PSUs work correctly. Lastly, you may want to get a 1 to 8 PWM fan hub to connect the 7 chassis fan to the motherboard fan header so that you can control the speed/sound of the server. If you have the fans hooked up to the SAS expander, they run at full speed and are NOISY. Yes, the 4U SuperMicros can fit a standard ATX motherboard, you'll need a special chassis control panel to I/O port breakout cable (it's about $20 on Amazon/eBay) if you're not using a SuperMicro motherboard.
  13. I would get a 9207+ series, it uses PCIe 3.0 ... and in some cases cheaper than the classic 9211-8i which is PCIe 2.0. For hard drives it doesn't matter, but helps if you have SSD caches on the controller. I picked up my controller from the seller qbtl on eBay... his cards seem to be fine, been using a 9211-8i from that seller for about 3 years no issues and just ordered a 9207-8i (waiting for it to come in the mail).
  14. Even with a SAS2 or SAS3 port expander it should have full bandwidth per drive (about 125MB/s). If you get a dual port SAS2 expander that's 48gbps over 24 drives which is 250MB/s right (with SAS and PCIe overhead I guess around 200MB/s?).
  15. Aquantia based cards are pretty cheap and work well with unRAID. How much did you pay for your card?
