hi, all i want to replace a ost, and i read the manual(820-3681.pdf from sun site), i get this section 4.2.3.1 about how to do:
4.2.3.1 Removing an OST To remove an OST: 1. Deactivate the OST (make it read-only) on the MDS so no new objects are allocated to it. 2. Use lfs find to discover all files that have objects residing on the deactivated OST. 3. Copy these files to a new location and then move them back to their original location to force their object re-creation on the active OSTs and the object deletion on the OST to be removed. and i do as what it say, deactivate the ost(cfs-OST0003_UUID) at my MGS, and find the files reside in ost cfs-OST0003_UUID from my client, and copy the file...ouch, i can't copy the file, the error msg is: cp /data//v/ff/b6/0b142400670.flv ./ cp: cannot stat `/data//v/ff/b6/0b142400670.flv ': Input/output error because the ost is deactive, so i can't stat and read the file? how to do that? thanks for you help. -- Best regards Felix New _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
