Good morning, group: On 2022-02-06 I purchased 4 WD Red 2T 5400rpm hard drives from Amazon for the MediaSonic Pro external hard drive.
The two drives in slots 3 and 4 were combined into a logical volume and used for daily dirvish backups. Earlier this year the LV failed. I repartioned those two drives and installed xfs on them because that's what pros here recommended. Now the drive in slot 3 (/dev/sde1) is mounted on /media/bkup1 and the drive in slot 4 (/dev/sdf1) is mounted on /media/bkup2. Each night, at 00:30 root's crontab runs the dirvish backup; at 01:00 a crontab script rsync's /media/bkup1 to /media/bkup2. About a week ago (I forget the exact date) as I prepared to log in to my desktop server/workstation I found a long display of /dev/sde1 errors on the console. The kernel (I assume) told me to umount /dev/sde1 and run xfs_repair on that drive. After reading the xfs_repair man page that's what I did. This morning I found a shorter message about an error on /dev/sde1 when I woke up the monitor. Another run of xfs_repair put the drive back to what it should be. I assume that WD Red drives are supposed to last more than 16 months so I could contact them about it. However, since daily incremental backups are critical for my business I'm asking for your professional advice: should I replace that drive (perhaps both backup drives)? If so what brand/model should I purchase? My internal hard drive is 2T so all the external hard drives are 2T. All previous external backup drives have been the size of the internal drive so I don't think a larger drive is warranted. Reccomendations wanted. TIA, Rich
