Hi, i breaked xfs_repair and lauched it again. On beginning of phase 6 i have failed to create prefetch thread: Resource temporarily unavailable https://download.bcom.cz/xfs/Screenshot_20230130_114707.jpeg Also, there is dmesg, when it was trying to mount it and it was stuck https://download.bcom.cz/xfs/dmesg.txt Libor From: Libor Klepáč <libor.klepac@xxxxxxx> Sent: Thursday, January 26, 2023 11:46 To: linux-xfs@xxxxxxxxxxxxxxx <linux-xfs@xxxxxxxxxxxxxxx> Subject: xfs_repair on filesystem stuck in "rebuild AG headers and trees"? Hi, we have virtual machine with 8TB data disk with around 5TB of data in few large files (backup repository of nakivo backup solution - it contains snapshots of vmware machines - one file per snapshot). We have recently upgraded VM from ubuntu 20.04 to ubuntu 22.04 and after reboot, mount of this filesystem took ages. I started xfs_repair on it and now it spits line rebuild AG headers and trees - 16417 of 16417 allocation groups done in 15 minutes interval for last two days. Is it in loop? Can i break it? Data on disk is just remote copy of backup, so it can be lost, it will just take some time to transfer it again. Kernel is probably from package 5.15.0-58.64 - sorry i don't know real version, cannot get it from ubuntu package. xfsprogs should be 5.13.0-1ubuntu2 Thanks for any info, with regards, Libor
