# lfs getstripe 129-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
warning: cb_getstripe: 129-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX does not exist: No such file or directory (2)
In liblustreapi's cb_getstripe() the lumlen member of param is initialized to the max_easize read from /proc/fs/lustre/llite/*/max_easize. This can cause truncation of the basename before ioctl() is called:
strncpy((char *)¶m->lmd->lmd_lmm, fname, param->lumlen);
The underlying IOC_MDC_GETFILESTRIPE ioctl() handles this (mostly) correctly.
