I am a system engineer that was attracted to nilfs due to some of the features that the file system already has. I talked one of our developers into doing a performance test against our in house software application that is running in a nilfs partition. My issue is that the host server continues to lockup during the performance test. I thought it may have something to do with the server itself, but the performance test runs successfully on the server on the same harddrive in a different partition. My question is what can I do to monitor and log what the issue is since the only way to get back into the machine is to do a hard power cycle. I have turned on debug in the nilfs_cleanerd config file and I am capturing the log to a separate location. The lockup seems to occur right after a "2 segments selected to be cleaned" message was sent.
gentoo distribution 2.6.30 kernel x86 nilfs-utils 2.0.12 partition 466GB application is postgresql, sqlite and lucene and python all db's and indexes are being written into the nilfs partition so there are tons of file changes happening at all times during the test. During the test, the file system is growing at a rate of 3 MB/sec and the test runs for greater than 4 hours straight. The total data the test writes is about 1.4 gig when it completes, but as I stated in before, most of the data is in lucene indexes, postgresql and sqlite db's. I am under the impression that our application is hammering the file system with too many read and write requests at the same time. Thanks for any suggestions, James... _______________________________________________ users mailing list [email protected] https://www.nilfs.org/mailman/listinfo/users
