search for: seeki

Hello, This patch fixes a problem where we end up seeking too much when *last_ptr is valid. This happens because btrfs_lookup_first_block_group only returns a block group that starts on or after the given search start, so if the search_start is in the middle of a block group it will return the block group after the given search_start, which is suboptim...

CFQ considers it seeky (*), BFQ doesn't. As a side effect BFQ does not always dispatch enough requests to correctly detect tagging. At the first seek you cannot tell if the process is going to bee seeky or not, and we have chosen to consider it sequential because it improved fairness in some sequential workloads (the CIC_SEEKY heuristic is used also to determine the idle_window length in

Hullo! First mail, sorry if this is the wrong place for this kind of question. I realise this is a "piece of string" type question. tl;dr version: I have a resizefs shrinking an ext4 filesystem from ~4TB to ~3TB and it's been running for ~2 days. Is this normal? Strace shows lots of:- lseek(3, 42978250752, SEEK_SET) = 42978250752 read(3,

Hello everyone, Btrfs v0.13 is now available for download from: http://oss.oracle.com/projects/btrfs/ We took another short break from the multi-device code to make the minor mods required to compile on 2.6.25, fix some problematic bugs and do more tuning. v0.13 has no disk format changes since v0.12. The most important fix is for file data checksumming errors. These might show up on .o

I have tried many permutations of search terms in google and I haven't been able to find any confirmation that the megaraid* modules in centos4 supports port multipliers/multiplexers. Here is a link to the controller I have in mind at newegg: http://www.newegg.com/product/product.asp?item=N82E16816118032 In case anyone is interested, here is what my research has turned up when looking for

Hello everyone, Btrfs v0.16 is available for download, please see http://btrfs.wiki.kernel.org/ for download links and project information. v0.16 has a shiny new disk format, and is not compatible with filesystems created by older Btrfs releases. But, it should be the fastest Btrfs yet, with a wide variety of scalability fixes and new features. There were quite a few contributors this time
