Hi Dag, > Just had a fight with this myself, also using Seagate drives. > And I don't think he needs to loose any data, nor use ddrescue here. What a coincidence! thank you for your advice. But sorry, dd_rescue is now running on my PC. (Thank you Mikael) Looking at the progress, it will take about 12 hours more to finish copying. To move the 112 "Pending" sectors to "Reallocated_Sector_Ct" in sdb, redundancy drive is required? I don't know whether it works or not in my case. >> Also check why you didn't get notification that sdc wasn't part of the >> array, usually mdmon or equivalent will send email about these events. > > Good advice! Set up the smartctl email address! Not mdadm.conf but smartctl? I added "MAILADDR" entry (mailing list in my dept.) to /etc/mdadm.conf, and mdmonitor service was running. But no notifier e-mail was delivered to the list. There is a mail server issue in my company. :( Anyway now I set my personal e-mail address to MAILADDR and found notifier works.
