curtis-r Posted March 28, 2020 Share Posted March 28, 2020 (edited) There are many threads on speed issues, but I've found no resolve with my issue; which I've noticed on multiple occasions over time. When copying large (>40GB) files to my unraid from my Win7x64 desktop, transfers start off @ 40-75 MB/s. After some time (<30 minutes) drops to <800 kB/s. If I pause & restart the transfer, jumps up for a while then drops again to <10 MB/s. As of recent, these large transfers end up causing errors in my parity. I rebuilt it 2 days ago & all was good. Now after another batch of transfers, 2304 parity errors. Ran iperf (results attached). Looks good to me. Also attached diagnostics file. Gigabit switch. Cat6 cables. Tested cables for continuity. Any help would be greatly appreciated. ipef3 tests on unraid.txt tower-diagnostics-20200328-1005.zip Edited March 28, 2020 by curtis-r forgot to include parity errors. Quote Link to comment
JorgeB Posted March 29, 2020 Share Posted March 29, 2020 Parity dropped offline: Mar 27 17:28:14 Tower kernel: ata11: softreset failed (1st FIS failed) Mar 27 17:28:14 Tower kernel: ata11: reset failed, giving up Mar 27 17:28:14 Tower kernel: ata11.00: disabled Mar 27 17:28:14 Tower kernel: ata11: EH complete Mar 27 17:28:14 Tower kernel: sd 11:0:0:0: [sdi] tag#8 UNKNOWN(0x2003) Result: hostbyte=0x04 driverbyte=0x00 Mar 27 17:28:14 Tower kernel: sd 11:0:0:0: [sdi] tag#8 CDB: opcode=0x8a 8a 00 00 00 00 01 50 db ed 40 00 00 04 00 00 00 Mar 27 17:28:14 Tower kernel: print_req_error: I/O error, dev sdi, sector 5651557696 Mar 27 17:28:14 Tower kernel: md: disk0 write error, sector=5651557632 Since it dropped there's no SMART, so check/replace cables and post new diags. Also performance wise (and for other reasons) would be a good idea to convert all your reiserfs disks, reiserfs it's not recommended for years now. Quote Link to comment
curtis-r Posted March 29, 2020 Author Share Posted March 29, 2020 Will do on the cables. I did not know unraid could do a different file structure than reiserfs. Is there documentation on how to convert that? A search didn't produce anything. Thanks Quote Link to comment
