Hard disk : Unrecovered read error - auto reallocate failed
Hi,
Some months ago I installed a new hardrive in a SATA array for our file server (Nethserver 7, CentOS 7)
Recently I noticed some errors messages in the system console :
Oct 1 01:00:21 serveur kernel: sd 3:0:0:0: [sdb] FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE

However, the RAID array is marked as CLEAN. The SMART status of the drive looks close to perfection too :
Status of drive /dev/sdb
Location SATA device B Drive size 1.86 TB
Make and model ATA WDC WD20EZRZ-00Z Supports SMART? Yes
SMART enabled? Yes Passed drive check? Yes
Model family Western Digital Blue Make and model WDC WD20EZRZ-00Z5HB0
Serial number WD-WCC4N0XCN61X Capacity 2,000,398,934,016 bytes [2.00 TB]
Additional SMART attributes
Offline data collection status Offline data collection activity was suspended by an interrupting command from host.
Auto Offline Data Collection: Enabled.

Anybody could explain what's going on ? Since the drive is new, should I send it to warranty ?
Thank you very much.
