Hello, I'm running FreeBSD 9.0/amd64, pure ZFS setup, one Seagate disk ST2000NM0011 SN02 on LSI Logic (mpt) controller. Yes, I know that running one disk on RAID controller is a bit weird, I have to find yet if it is possible to connect disk to internal SATA controller. About two days ago, system became SLOW. Disk usage is constantly 100%, and sometimes I'm getting swap_pager: indefinite wait buffer error. I had to reset computer twice in two days. mptutil does not show any errors, and smartctl shows SMART Attributes Data Structure revision number: 10 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x000f 067 063 044 Pre-fail Always - 6218970 3 Spin_Up_Time 0x0003 093 092 000 Pre-fail Always - 0 4 Start_Stop_Count 0x0032 100 100 020 Old_age Always - 14 5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 21 7 Seek_Error_Rate 0x000f 091 060 030 Pre-fail Always - 1433294073 9 Power_On_Hours 0x0032 090 090 000 Old_age Always - 8825 10 Spin_Retry_Count 0x0013 100 100 097 Pre-fail Always - 0 12 Power_Cycle_Count 0x0032 100 100 020 Old_age Always - 16 184 End-to-End_Error 0x0032 100 100 099 Old_age Always - 0 187 Reported_Uncorrect 0x0032 100 100 000 Old_age Always - 0 188 Command_Timeout 0x0032 100 099 000 Old_age Always - 12885098499 189 High_Fly_Writes 0x003a 100 100 000 Old_age Always - 0 190 Airflow_Temperature_Cel 0x0022 068 047 045 Old_age Always - 32 (Min/Max 31/32) 191 G-Sense_Error_Rate 0x0032 100 100 000 Old_age Always - 859 192 Power-Off_Retract_Count 0x0032 100 100 000 Old_age Always - 15 193 Load_Cycle_Count 0x0032 100 100 000 Old_age Always - 26 194 Temperature_Celsius 0x0022 032 053 000 Old_age Always - 32 (0 21 0 0 0) 195 Hardware_ECC_Recovered 0x001a 103 099 000 Old_age Always - 6218970 197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 0 198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age Always - 0 SMART Error Log Version: 1 No Errors Logged I have removed most of snapshots, it does not help. I have stopped all active processes, disk load did not decrease, same 100%. What can I check and/or replace to get the problem fixed? Any ideas? Alex
