Red Hat Bugzilla – Bug 1001856
Erroneous disk failing alert
Last modified: 2017-12-06 05:33:06 EST
Description of problem: palimpsest reports that DISK HAS MANY BAD SECTORS In fact it claims that there are 1441814 reallocated sectors. smartctl shows on 22 reallocated sectors and smart status as PASS. Interestingly, 1441814 = 0x160016, 22 = 0x16 I believe that the 'DISK HAS MANY BAD SECTORS' claim is bogus.

Red Hat invites you to ask your support representative to propose this request, if appropriate, in the next release of Red Hat Enterprise Linux.
In case anyone does want to fix the bug I have some more information. The disk in question is now reporting the following SMART data (summarised) ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x002f 100 092 016 Pre-fail Always - 0 2 Throughput_Performance 0x0027 136 100 054 Pre-fail Always - 95 3 Spin_Up_Time 0x0023 122 100 024 Pre-fail Always - 307 (Average 312) 4 Start_Stop_Count 0x0022 100 100 000 Old_age Always - 44 5 Reallocated_Sector_Ct 0x0033 100 100 005 Pre-fail Always - 43 (0 43) ... 196 Reallocated_Event_Count 0x0032 100 100 000 Old_age Always - 43 197 Current_Pending_Sector 0x0032 100 100 000 Old_age Always - 1 Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Short offline Completed: read failure 60% 8044 88304445 And palimpset now says that the 5 - Reallocated Sector Count is 2818091. 2818091 = 0x2B002B 0x2B = 43 Attribute 5 and 196 are now both reading 43. The disk now has 1 unreadable sector but the Reallocated Sector Count is still bogus and the pattern in the error seems consistent. I will try and get this fixed upstream.
