Yup, fstrim isn't supported (by the kernel) in RHEL 6: ><rescue> mke2fs -t ext4 /dev/sda1 mke2fs 1.41.12 (17-May-2010) [...] ><rescue> mount /dev/sda1 / [ 75.237242] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: ><rescue> fstrim / fstrim: /: FITRIM ioctl failed: Inappropriate ioctl for device ><rescue> strace fstrim / [...] ioctl(3, 0xc0185879, 0x7fff0dcc0940) = -1 ENOTTY (Inappropriate ioctl for device) [...] Thus this error message is correct. However we could remove/disable the fstrim API completely from libguestfs, although I'm not really sure that would help anyone. Anyone running the guestfish fstrim command blindly would get an error in both cases. |
Description of problem: fstrim returns error "FITRIM ioctl failed: Inappropriate ioctl for device" in rhel6, through its help output, "If this support isn't present it may give an error or even appear to run but do nothing" we are not sure, whether it's not support or it's a bug Version-Release number of selected component (if applicable): libguestfs-1.20.9-6.el6.x86_64 kernel: 2.6.32-358.el6.x86_64 qemu-kvm-0.12.1.2-2.375.el6.x86_64 How reproducible: 100% Steps to Reproduce: [root]# qemu-img create -f qcow2 test.qcow2 100M [root]# guestfish -a test.qcow2 ><fs> run ><fs> mkfs ext2 /dev/sda ><fs> mount /dev/sda / ><fs> df Filesystem 1K-blocks Used Available Use% Mounted on tmpfs 98036 0 98036 0% /run /dev 241996 128 241868 1% /dev /dev/sda 99150 1550 92480 2% /sysroot ><fs> fstrim / libguestfs: error: fstrim: fstrim: /: FITRIM ioctl failed: Inappropriate ioctl for device Actual results: fstrim give an error Expected results: fstrim works well Additional info: in rhel7, fstrim does not give error but do nothing, ><fs> df Filesystem 1K-blocks Used Available Use% Mounted on tmpfs 97952 76 97876 1% /run /dev 243196 0 243196 0% /dev /dev/sda 99150 1550 90432 2% /sysroot ><fs> fstrim / ><fs> df Filesystem 1K-blocks Used Available Use% Mounted on tmpfs 97952 76 97876 1% /run /dev 243196 0 243196 0% /dev /dev/sda 99150 1550 90432 2% /sysroot
