RayD Posted September 2, 2019 Share Posted September 2, 2019 (edited) Hello - I'm seeing very slow speeds during a rebuild and I'm wondering if it's simply my setup, as I'm new to this. I'm seeing about ~1.1mb/sec to a esata enclosure with 3 drives off of a PCIe card. I don't have much data yet, but am seeing about 40 days to rebuild. Is this normal?

itimpi Posted September 2, 2019 Share Posted September 2, 2019 You are getting continual reset and subsequent retries on a couple of the drives and that explains the slow speed. Normally with a standard SATA connection one would suspect a cabling issue, but in the case of an eSAtA enclosure I am not sure if this is still the case or whether the issue is with the enclosure itself.

RayD Posted September 5, 2019 Author Share Posted September 5, 2019 Appreciate the reply. I've been slowly taking each item out of the chain and swapping it out - finally leaving the enclosure, of which a warranty replacement is due in tomorrow. Quote Link to comment
JorgeB Posted September 5, 2019 Share Posted September 5, 2019 The 6 or 10 port Asmedia controller your using is in fact a 2 port controller with SATA port multipliers, these are known to give constant timeouts and should be avoided. Quote Link to comment
RayD Posted September 7, 2019 Author Share Posted September 7, 2019 Excuse my ignorance, but I'm using one of these: https://www.amazon.com/gp/product/B07595M2MK/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 Should I not be using this? I've replaced the eSATA enclosure, but still have "error" instead of "healthy" on the 3 drives. I've erased, started a new configuration, and seem to be in the same spot - though it's all running. I've replaced the PCI eSATA card, 90 deg header, and enclosure. Only the drives themselves and the motherboard/PC are the same as when I began. With a small wiggle of the eSATA cable going into the enclosure I can make the activity lights dance, so I've ordered a replacement cable next. I've attached another diagnostic zip in case I'm missing something (likely). tower-diagnostics-20190907-0144.zip Quote Link to comment
JorgeB Posted September 7, 2019 Share Posted September 7, 2019 The controller is fine, but it's connected to a SATA port multiplier, that would be on the enclosure, those are not recommended, though they can work in some rare cases. Quote Link to comment
RayD Posted September 7, 2019 Author Share Posted September 7, 2019 Ah, thank you. Well that's unfortunate. I have a 1U rack PC without much room inside for straight SATA - do you have any suggestions with this hardware set up - eSATA is not an option? Quote Link to comment
JorgeB Posted September 8, 2019 Share Posted September 8, 2019 I don't recommend eSATA with port multipliers or USB for external enclosures, if external is needed use SAS, more expensive but 100% reliable. Quote Link to comment
RayD Posted September 8, 2019 Author Share Posted September 8, 2019 One more question - with the attached diagostics file, how can I see why the three drives in the enclosure are in error on the Dashboard tab in the GUI? Everything I'm looking at says pass, they're green on the main tab, and everything appears to be functioning. Thanks, again. tower-diagnostics-20190908-1242.zip Quote Link to comment
JorgeB Posted September 9, 2019 Share Posted September 9, 2019 There's not much to see since the diags are just after a reboot, but there's already one timeout error: Sep 7 21:53:46 Tower kernel: ata8.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen Sep 7 21:53:46 Tower kernel: ata8.00: failed command: WRITE DMA EXT Sep 7 21:53:46 Tower kernel: ata8.00: cmd 35/00:40:20:5a:5b/00:05:ae:01:00/e0 tag 11 dma 688128 out Sep 7 21:53:46 Tower kernel: res 40/00:01:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) Sep 7 21:53:46 Tower kernel: ata8.00: status: { DRDY } Sep 7 21:53:46 Tower kernel: ata8: hard resetting link Sep 7 21:53:46 Tower kernel: ata8: SATA link up 6.0 Gbps (SStatus 133 SControl 300) Sep 7 21:53:46 Tower kernel: ata8.00: configured for UDMA/133 Sep 7 21:53:46 Tower kernel: ata8: EH complete ATA8 is disk1 Quote Link to comment
