January 22, 20251 yr So, i've had a lot of issues the past week with my Unraid system. It all started with slow read/write speeds. Iperf showed a good 1 gbps connection and diskspeed showed that my disks where performing good. Then I got a lot of errors in my syslog saying: Jan 21 02:34:27 itxserver kernel: ata6: COMRESET failed (errno=-16) Jan 21 02:34:27 itxserver kernel: ata6: hard resetting link Jan 21 02:34:29 itxserver kernel: ata6: SATA link up 1.5 Gbps (SStatus 113 SControl 310) Jan 21 02:34:29 itxserver kernel: ata6.00: configured for UDMA/33 Jan 21 02:34:29 itxserver kernel: ata6: EH complete Over and over again during read/write. I then checked moved my SATA cables around and i think this error corresponds to my disk5 (TOSHIBA_MG09ACA18TE_Y430A057FJDH 18TB). After I booted up again I didn't get the ata6 error, but the speeds where still slow (50 mb/s read, 18 mb/s write). After another reboot my disk5 now says: "Unmountable: Wrong or no file sysem". What do I do now? I do have pairity. Do i re-format the drive and re-create it from parity? Thank you! This has been a nightmare for days now. itxserver-diagnostics-20250122-1920.zip Edited January 22, 20251 yr by Storken

Phase 2 - using internal log - zero log... ALERT: The filesystem has valuable metadata changes in a log which is being ignored because the -n option was used. Expect spurious inconsistencies which may be resolved by first mounting the filesystem to replay the log. - scan filesystem freespace and inode maps... - found root inode chunk Phase 3 - for each AG... - scan (but don't clear) agi unlinked lists... - process known inodes and perform inode discovery... - agno = 0 - agno = 1 - agno = 2 - agno = 3 - agno = 4 - agno = 5 - agno = 6 - agno = 7 - agno = 8 - agno = 9 - agno = 10 - agno = 11 - agno = 12 - agno = 13 - agno = 14 - agno = 15 - agno = 16 - process newly discovered inodes... Phase 4 - check for duplicate blocks... - setting up duplicate extent list... - check for inodes claiming duplicate blocks... - agno = 0 - agno = 1 - agno = 7 - agno = 2 - agno = 5 - agno = 3 - agno = 4 - agno = 6 - agno = 8 - agno = 9 - agno = 10 - agno = 11 - agno = 12 - agno = 13 - agno = 14 - agno = 15 - agno = 16 No modify flag set, skipping phase 5 Phase 6 - check inode connectivity... - traversing filesystem ... - traversal finished ... - moving disconnected inodes to lost+found ... Phase 7 - verify link counts... Maximum metadata LSN (1:1540509) is ahead of log (1:1536657). Would format log to cycle 4. No modify flag set, skipping filesystem flush and exiting. Should I press "Fix"?

January 22, 20251 yr Author Just now, JorgeB said: Is that read/write to the array? Yes. SMB shares. I've tried diffrent PC's all wirered rj45.
January 22, 20251 yr Community Expert Start by running a single stream iperf test in both directions to rule out any network issues.

January 22, 20251 yr Author PC: 192.168.1.152 Unraid server: 192.168.1.101 I seem to only get 350 Mbits/s when Unraid acts as the iperf server.. hmm, conslutions?
January 23, 20251 yr Author 1 hour ago, JorgeB said: That suggests a network issue, or a client problem I don't even know where to begin. It's the same speed with a ethernet cable directly between the PC and the Unraid server. It must be a server problem. Same with every PC i try.
January 23, 20251 yr Community Expert It could be for exaple a problem with the server NIC or NIC driver, but since iperf shows an issue, it must be LAN related.
