Hi team,

I met the NODE has failed disks problem,those disks are all offline.

I'm afraid my data will lose.

As the tips said,looking at /opt/mapr/logs/faileddisk.logs. But the faileddisk.logs doesn't exist.

/opt/mapr/server/mrconfig sp list

ListSPs resp: status 0:1

No. of SPs (1), totalsize 0 MB, totalfree 0 MB

SP 0: name SP1, Offline, size 420033 MB, free 0 MB, path /dev/sdb1

Then i traced the mfs.log and found the following errors

2013-02-27 08:48:15,9229 ERROR x.x.0.0:0 SP SP1:/dev/sdb1 online failed,
it was previously marked with disk ERROR 19.
To bring it online first repair the SP using fsck utility.

**1) How to use fsck utility to repair the SP? How to bring it online?**

**2) What lead to  SP offline?**

**3) Does SP offline lead to data lose?**
