Can not find .data file on the instance's datastore/0_persistent folder


#1

As I try to figure out the disk consumption of a particular array, I check the datastore/0_persistent directory. But all other .data file are there except the one I’m concerned with. Does anyone know what’s the probable cause of these problem?

p.s I can show that array in iquery, but just can not see where it is stored.

Hi @impanyu,
How many instances are in your SciDB cluster? Which version of SciDB are you running? Depending on the size of the array, not all instances may have chunks for your array. Can you check for the data file in other instances of your cluster?
Thanks,
Dave

It turns out my array partition are too coarse grained, so only a small fraction of instance get filled with the data. Now I’ve adjusted the partition and made the array load balancing.
