[Lustre-discuss] lfsck

[Charles Taylor]

Here is a question (or perhaps a veiled comment/complaint).     Why  
does lfsck list *every* file name to stderr?    Doesn't that just make  
a painfully slow process even slower?    Would it be better to just  
report progress periodically and any *important* errors that need to  
be addressed.

So far on a 33TB file system (8 OSSs, 24 OSTs), the time required has  
been....

Generate mdsdb:    6.5 hours  (94GB, sparse)
Generate ostdbs:    45 mins each (400 to 600 MB each)
Copying db's   around :   45 min to an hour
Actual LFSCK:   ?????  (an hour so far but we have 30,600,000 files  
(roughly) so I fear this will get ugly.

I'm not making any real point here - just sharing information and,  
well, killing time... :)
