I've run 2.4.20 for a long time, and have been seriously plagued with the I/O stalls. On a file server (details below) here I upgraded to 2.4.21-rc6 yesterday. The I/O stalls have *almost* gone away. Best of all, we still have our data intact ;) Server data: ~130 GB data on a ~150 GB ext3fs with >1 million files Software RAID-0+1 on four IDE disks Two promise controllers 1x20262 1x20269 1x Intel eepro100, 1x Intel e1000 dual PIII, half a gig of memory NFS server (mainly v3, many different clients) > > After the long obscure problems since 2.4.19x, -rc6 could use serious > stress-testing. This server rarely has load below 1, but frequently above 15. It may run some compilers and linkers locally, but most of the load comes from NFS serving. So far it's been running for 28 hours with that kind of load. Nothing suspicious in the dmesg yet. I will of course let you all know if it falls on it's knees. So far it's all thumbs-up from me! There may still be an occational stall here and there, but compared to 2.4.20 this is heaven (it really was unbelievably annoying having your emacs stall for 10 seconds every 30 seonds when someone was linking on the cluster) :) A big *thank*you* to Marcelo for deciding to include a fix for the I/O stalls! -- ................................................................ : jakob@unthought.net : And I see the elder races, : :.........................: putrid forms of man : : Jakob ?stergaard : See him rise and claim the earth, : : OZ9ABN : his downfall is at hand. : :.........................:............{Konkhra}...............: - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
