Btrfs - 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? #btrfs #data #corruption #loss #cow #linux #filesystem #shutdown

"Surfin' U.S.A." is a song by the American #rock band #theBeachBoys, credited to #ChuckBerry and #BrianWilson. It is a rewritten version of Berry's "#SweetLittleSixteen" set to new lyrics written by Wilson and an uncredited #MikeLove. The song was released as a single on March 4, 1963, backed with "#ShutDown". It was then placed as the opening track on their album of the same name.

Подготовил тред для беженцев в связи с закрытием lor.sh.

Хочется сделать ультимативную точку обмена информацией по поводу того куда бежать, что можно захостить самостоятельно и где кого найти. Ну и плюс ответы на технические вопросы и посильная помощь, если кому нужна.

Но у меня дилемма:

1. Я могу запостить это здесь СЕЙЧАС, но тогда этот тред, скорее всего, канет в небытие вместе с lor.sh когда сервер будет выключен.

2. Я могу запостить это ПОЗЖЕ (несколько дней, неделя) со своего нового инстанса - селфхост или паблик, неважно - этот пост будет доступен и после того как lor.sh перестанет работать.

Если вы заинтересованы в таком треде, то проголосуйте в опросе. Если нет - просто используйте показ результатов если вам интересно.

While they were together, I hope they did "Shut Down."

Junior Brown's "Surf Medley" is must listening.

He's an amazing guitarist who doesn't get anywhere near his due.

TIL: an exhausted #cmos #battery can cause #Linux to behave strangely after a hard #shutdown (caused by a #UPS being incorrectly turned off) - it uses the BIOS time to check the filesystem block timestamps, and as it had gone back to 2012 the OS thinks the filesystem time is in the future! (At least the hard drive on this server isn't on the way out yet which is what I had feared, but this required an emergency visit to the office as it is the main #VOIP #PBX) #sysadmin
