Hi, Thanks in advance for looking this query and hoping for some help from = File system experts. We have a RAID 0 volume which has partition (created using sysinstall fdisk= option). While IOs are in progress removing one of the volume member kernel panic is= hit with the following messages g_vfs_done():(da0:da0s1d[WRITE(offset=3D6358872064, length=3D2048)]mpslsi0:= 0:error =3D 6 0:/home: got error 6 while accessing filesystem 0): panic: softdep_deallocate_dependencies: unrecovered I/O error lost device Note: 1. The issue is also seen on a RAID 0 volume which does not have a partitio= n on it. 2. Issue was observed on both SAS and SATA drives. 3. When we send IOs to the driver without FS (using "dd" command), kernel p= anic never seen. I have searched on this topic and looks like something wrong with FS. _but_= I don't have any trigger to support that this is not Driver issue. When we tried below options: (disable Journal on FS) Things does not change= . We still see kernel panic. umount <filesystem> tunefs -j disable <filesystem> mount <filesystem> cd <filesystem> rm .sujournal Any thoughts ? ` Kashyap
