enableAdvancedRASplitCost() does the same thing as ConsiderLocalIntervalCost, but as a subtarget option instead of a command-line option, and as I’ve said it doesn’t help because it’s a non-local interval causing the eviction chain (RAGreedy::splitCanCauseEvictionChain only considers the local interval for a single block, and it’s unclear to me how to make it handle a non-local interval).

Hi! We''ve started to poke and prod at Lustre 1.6.4.1, and it seems to mostly work (we haven''t had it OOPS on us yet like the earlier 1.6-versions did). However, we had this weird incident where an active client (it was copying 4GB files and running ls at the time) got evicted by the MDS and all OST''s. After a while logs indicate that it did recover the connection to the MDT, but not the OST''s ... lctl ping between the client and mds/oss''s still worked. After a while I got tired of waiting for it to recover and did umount -f, which also h...

Hi, Can a dbuf be in DB_CACHED state, db_holds == 0, b_efunc != NULL while its db_buf is put on the eviction list ? From an ASSERT in dbuf_do_evict(), it appears that it can. If it can, I am wondering what is preventing the following race dbuf_hold_impl() db = dbuf_find(dn, level, blkid); ... if (db->db_buf && refcount_is_zero(&db->db_holds)) { arc_b...

Hi, I have also posted this on GitHub but it isn?t clear that was the right place: https://github.com/WayneD/rsync/issues/522 iCloud Drive will evict files that are unused or when additional space is needed on the local drive.

...n short, we move out the low level content of a buffer object. In the case of textures and such this is utterly useless. Still it is accessed, because ttm sees no problem in using PL_SYSTEM or PL_TT memory. What is the best way to let ttm know we don't really appreciate that? A custom memory to evict to that cannot be mapped maybe. Or an extension of PL_SYSTEM or PL_TT. Share your ideas. Maarten.

Currently, we take down the sgdma engine without evicting all buffers from VRAM. The TTM device release will try to evict anything in VRAM to GART memory, but this will fail since sgdma has already been taken down. This causes an infinite loop in kernel mode on module unload. It usually doesn't happen because there aren't any buffer on close....

Should I be seeing messages like: Dec 14 12:06:59 nyx170 kernel: Lustre: MGS: haven''t heard from client dadccfac-8610-06e7-9c02-90e552694947 (at 141.212.30.185 at tcp) in 234 seconds.

The file system (i would hope) would be unmounted before the network device goes down when i put in _netdev in fstab. Or will I still see these message when the client shuts down? Brock P...

...all Gige and has about 608 nodes 1854 cores. We have allot of jobs that die, and/or go into high IO wait, strace shows processes stuck in fstat(). The big problem is (i think) I would like some feedback on it that of these 608 nodes 209 of them have in dmesg the string "This client was evicted by" Is this normal for clients to be dropped like this? Is there some tuning that needs to be done to the server to carry this many nodes out of the box? We are using default lustre install with Gige.

...to keep the constant in a register for a single use! *** Live-Range Splitting Looking at the first constant, we can see that the copies are inserted by the greedy register allocator when it splits the live range. The main entry point is selectOrSplit. In brief: 1) The constant is assigned and evicted several times. Eventually selectOrSplit decides to split the live-range. This splits the interval in two, creating two new intervals (A and B). At the boundary of the intervals a copy is inserted that copies between the virtual registers. 2) The virtual register for the first interval (A) is...

The inode eviction can be very slow, because during eviction we tell the VFS to truncate all of the inode''s pages. This results in calls to btrfs_invalidatepage() which in turn does calls to lock_extent_bits() and clear_extent_bit(). These calls result in too many merges and splits of extent_state structu...

...and to get better behaviour with the page cache in some scenarios. For my testing I used the cachedel and cachestats utilities written by Julius Plenz (https://github.com/Feh/nocache). I started with a 32 GB file of random data on a machine with about 32 GB of RAM. At the beginning of the test I evicted the file from the page cache: $ cachedel /var/tmp/random $ cachestats /var/tmp/random pages in cache: 0/8388608 (0.0%) [filesize=33554432.0K, pagesize=4K] Performing a normal sequential copy of the file to /dev/null shows that the file is almost entirely pulled into page cache (thus evicting u...
