AptiviLinux might no longer support HFS/HFS+The antique filesystems, <a href="https://en.wikipedia.org/wiki/Hierarchical_File_System_(Apple)" rel="nofollow noopener noreferrer" target="_blank">HFS</a> and <a href="https://en.wikipedia.org/wiki/HFS_Plus" rel="nofollow noopener noreferrer" target="_blank">HFS+</a>, were used in old Macs going back to Septmber 17th, 1985, with the former being used first, then the latter. They also have alternative names, called Mac OS Standard and Mac OS Extended.During development of Mac OS X 10.6 Snow Leopard released in August 28th, 2009, Apple decided to stop all support for read-write HFS and HFS+ filesystems, making users be unable to write to any file, but they still could read from such volumes. In macOS Catalina, Apple finally removed the filesystem support from the Darwin kernel, making it impossible to use disks that are still formatted with such filesystems.We appear to have reached the end of support for the two antique filesystems in Linux, too, because, this year, the prominent Linux developer from Microsoft stated that, via <a href="https://mastodon.social/@brauner/114341096129808573" rel="nofollow noopener noreferrer" target="_blank">Mastodon</a>:<blockquote>Let’s try and remove <a href="https://mastodon.social/tags/hfs" rel="nofollow noopener noreferrer" target="_blank">#hfs</a> and <a href="https://mastodon.social/tags/hfsplus" rel="nofollow noopener noreferrer" target="_blank">#hfsplus</a> by the end of 2025. They have been orphaned since 2014 and are turning into a maintenance burden.</blockquote>If you’re still using those filesystems after the support ending period, there is a chance that you could use those filesystems again via user-space filesystems, except that you won’t have the same experience, including the lack of support of writing to files for HFS+.Photo by <a href="https://unsplash.com/@mimithian?utm_content=creditCopyText&utm_medium=referral&utm_source=unsplash" rel="nofollow noopener noreferrer" target="_blank">Mimi Thian</a> on <a href="https://unsplash.com/photos/woman-sitting-on-sofa-while-using-macbook-pro-BYGLQ32Wjx8?utm_content=creditCopyText&utm_medium=referral&utm_source=unsplash" rel="nofollow noopener noreferrer" target="_blank">Unsplash</a><a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/filesystem/" target="_blank">#Filesystem</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/hfs/" target="_blank">#hfs</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/hfs-2/" target="_blank">#HFS_</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/kernel/" target="_blank">#Kernel</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/linux/" target="_blank">#Linux</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/linux-kernel/" target="_blank">#LinuxKernel</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/news/" target="_blank">#news</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/tech/" target="_blank">#Tech</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/technology/" target="_blank">#Technology</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/update/" target="_blank">#update</a>

Sami LehtinenBtrfs - Most curious case, is this flaw or not. Can't really tell. - I've got lots of scattered data in dirty write buffers to disk, due to scattered writes and high system memory. I've also got long commit interval to allow efficient flushing (as contiguous as possible) when that scattered data is finally written to disk. It all works fine, if I sync before shutdown. But if I just shutdown the system, the flush process takes longer than the maximum allowed file system unmount time is. Even worse, some of the data is written to SSD and some to HDD. The state data is on SSD and actual data is on HDD. When the flush timeout is encountered, the system shuts down in state where state file says that this data is written to disk, and the data actually isn't on disk yet. - Flaw or not? - Of course this requires this curious combination of things to trigger, but the problem is very real. - Who's fault it is? <a class="hashtag" href="https://pleroma.envs.net/tag/btrfs" rel="nofollow noopener noreferrer" target="_blank">#btrfs</a> <a class="hashtag" href="https://pleroma.envs.net/tag/data" rel="nofollow noopener noreferrer" target="_blank">#data</a> <a class="hashtag" href="https://pleroma.envs.net/tag/corruption" rel="nofollow noopener noreferrer" target="_blank">#corruption</a> <a class="hashtag" href="https://pleroma.envs.net/tag/loss" rel="nofollow noopener noreferrer" target="_blank">#loss</a> <a class="hashtag" href="https://pleroma.envs.net/tag/cow" rel="nofollow noopener noreferrer" target="_blank">#cow</a> <a class="hashtag" href="https://pleroma.envs.net/tag/linux" rel="nofollow noopener noreferrer" target="_blank">#linux</a> <a class="hashtag" href="https://pleroma.envs.net/tag/filesystem" rel="nofollow noopener noreferrer" target="_blank">#filesystem</a> <a class="hashtag" href="https://pleroma.envs.net/tag/shutdown" rel="nofollow noopener noreferrer" target="_blank">#shutdown</a>

AptiviLinux 6.15’s exFAT file deletion performance boostedA recent development in the upcoming Linux 6.15 kernel has been spotted, because there was a big improvement to the exFAT file system implementation in relation to how it deletes the files when the “<code>discard</code>” mount option is used. This improvement significantly saves time as a test file after the merge has been deleted in 1.6 seconds, compared to more than 4 minutes of the total time taken.<a href="https://lore.kernel.org/lkml/CAKYAXd_E0eM8dfoU1HVQ+DW4YKMsrzfJbGTsQELjfy=R+omndw@mail.gmail.com/" rel="nofollow noopener noreferrer" target="_blank">This pull request</a> makes sure that, upon file deletion, it discards a group of contiguous clusters (that is, clusters that are next to each other) in batch instead of discarding them one by one. This was because in prior kernels, such as 6.14, “if the discard mount option is enabled, the file’s clusters are discarded when they are freed. Discarding clusters one by one will significantly reduce performance. Poor performance may cause soft lockup when lots of clusters are freed.”The change has been introduced in commit <a href="https://web.git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/exfat.git/commit/?h=dev&id=a36e0ab44cb344728f7c0fdc34edcbae64739c16" rel="nofollow noopener noreferrer" target="_blank">a36e0ab</a>. Since then, the pull request has been merged to the kernel and it will be integrated to the first release candidate of Linux 6.15. A simple performance benchmark has been verified with the following commands:<pre><code># truncate -s 80G /mnt/file# time rm /mnt/file</code></pre>In detail, the performance of this filesystem without this commit is poor, totalling about 4 minutes and 46 seconds in real time, with 12 seconds of system time. In contrast to the patched kernel, it totals about 1 second in real time, with 17 milliseconds of system time.It’s a huge improvement!<a href="https://www.freepik.com/free-photo/pretty-woman-with-modern-laptop-sitting-floor-with-win-gesture-grey-wall_13814109.htm#fromView=image_search_similar&page=3&position=22&uuid=8eb92a45-4233-4174-8445-7ccb4fd07f7e&query=Laptop+sitting" rel="nofollow noopener noreferrer" target="_blank">Image by diana.grytsku on Freepik</a><a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/computers/" target="_blank">#Computers</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/exfat/" target="_blank">#exFAT</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/filesystem/" target="_blank">#Filesystem</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/kernel/" target="_blank">#Kernel</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/linux/" target="_blank">#Linux</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/linux-kernel/" target="_blank">#LinuxKernel</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/news/" target="_blank">#news</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/performance/" target="_blank">#performance</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/speed/" target="_blank">#speed</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/tech/" target="_blank">#Tech</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/technology/" target="_blank">#Technology</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://officialaptivi.wordpress.com/tag/update/" target="_blank">#update</a>
