One additional comment: The problem is NOT solved by rebooting. It seems that zeroing out is necessary :-(
hello! i have /dev/sdb 3TB
how to perform Zeroing the disk for 3TB
cat /dev/zero | pv -s 3000G | dd of=/dev/sda bs=100M
or this is not right ? please show the correct command
I'm afraid to make a mistake
Are you sure you have the same config as I (RAID1)?
Only in this case my howto makes sense, otherwise you will destroy all your data!!
If you are sure (really sure!) then the disk in the command must match:
cat /dev/zero | pv -s 3000G | dd of=/dev/sdb bs=100M
I think your can skip the zero-ing part. Unless you have write-intent bitmaps enabled, then just removing and re-adding a drive will cause MD to overwrite the entire disk, including your pending-bad blocks. Thiis has worked for me many times. Remember, though, that the SMART Offline_Uncorrectable won't get updated until the next offline collection occours, like with smartctl -t offline.
Thank your for your comment! I will try it our the next time I encounter the message!
